Hi All,
We have been facing lot of memory issues in production system and QA ECC ABAP only system after kernel upgrade from Basis 700 patch 310 to 347. Is there any known issue with this release? Users are not able to login then and there. We have all parameters set as per Note 146289 - Parameter Recommendations for 64-Bit SAP Kernel and Note 88416 - Zero administration memory management for the ABAP server. Our platform: 64 bit windows 2003 server/sql2005. I referred note Note 307976 - PXA_NO_SHARED_MEMORY and our abap buffersize is 1300000KB. Physical memory is 24GB. Do I have to increase the physical memory? System was much better before this kernel upgrade for add-on Vistex installation. Then so many memory related issues.
There are also other dumps like SYSTEM_CORE_DUMPED, STORAGE_PARAMETERS_WRONG_SET
"In the system profile, set the parameters
-abap/heap_area_dia and
-abap/heap_area_nondia
to a maximum of
1731363904. To be on the safe side, reduce the value by 10,000,
000."
But parameter values are kept standard from the above mentioned Notes. Please help ASAP.
Thanks,
Kavitha Rajan.

Hi,
Eduardo,
I am mostly getting PXA_NO_SHARED_MEMORY than STORAGE_PARAMETERS_WRONG_SET. Copying full dumps here.
I am copying full dump here.
Short text
1300000 kilo bytes of shared memory for PXA not available.
What happened?
When starting the R/3 System, 1300000 Kbytes of storage space
was required for the ABAP/4 program buffer (PXA), but this
was not available.
The system was started as an emergency system and is not fully
operational.
It is intended only for display and to eliminate errors.
Under no circumstances should it be used for production
purposes.

purposes.
used in production.
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrat
.
You can use the ABAP dump analysis transaction ST22 to view and manage
termination messages, in particular for long term reference.
Error analysis
The error probably occurred when installing the
R/3 system.
The return code of the SAP shared memory control was 1.
The error reported by the operating system is:
Error number..... 0
Error text....... "No error"
How to correct the error
Report the error to the group responsible for installing your
R/3 System.
The current size of the PXA was set at 1201980 kilobytes.
You can increase or decrease the PXA in the SAP profile. When
doing this, please refer to the relevent instructions in the
installation manual.
You can use the utility program 'ipclimits' to display the
available system resources.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"PXA_NO_SHARED_MEMORY" " "
"########################################" or
"########################################"
" "
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

The main program was " ".
In the source code you have the termination point in line 0
of the (Include) program "########################################".
The error occurred during initialization of the R/3 System.
Internal notes
The termination was triggered in function "ab_pbinit"
of the SAP kernel, in line 1909 of the module
"//bas/700_REL/src/krn/runt/abload3.c#58".
The internal operation just processed is " ".
Internal mode was started at "##############".
Second dump:
Short text
The system is configured incorrectly.
What happened?
The current program had to be terminated because of an
error when installing the R/3 System.
The program had already requested 1731363904 bytes from the operating
system with 'malloc' when the operating system reported after a
further memory request that there was no more memory space
available.
What can you do?
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
.
You can use the ABAP dump analysis transaction ST22 to view and manage
termination messages, in particular for long term reference.
In the system profile, set the parameters
-abap/heap_area_dia and
-abap/heap_area_nondia
to a maximum of 1731363904. To be on the safe side, reduce the value by 10,00
000.
Then restart the SAP system.
Error analysis
When the program was running, it was established that more
memory was needed than the operating system is able safely
to provide. To avoid a system crash, you must prevent this
situation from occurring.
How to correct the error
Report the error to the group responsible for installing your
R/3 System.

abap/heap_area_total = 17173577728
abap/heaplimit = 40000000
abap/buffersize = 1300000
Thanks,
Kavitha.
Hi kavitha,
You dnt have enough sapce in u r shred memory..,you can decrease ur abap/buffer size ,it will resolve u r problem..
Thanks

Hi Kavitha,
I have seen a lot of same messages before. In your message, you limit your system with(abap/heap_area_dia =2000000000) so if your dialog process use more than 2GB memory(EM...... 2002743520). It caused ABAP dump: PXA_NO_SHARED_MEMORY.
You can increase abap/heap_area_dia = 8,000,000,000 to 8GB if you want your dialog process use more memory. Beware this may cause more PXA_NO_SHARED_MEMORY errors if there are already two dialog processes consumed 8GB memory because you have only 16GB memory in total.

Hi Kavitha,
Could you take a reboot of the windows server.It should probably help.

Hi Kavitha,
Hope you updated DEV and QA before going for PRD . If the issue is not in those systems, its not a kernel issue I guess. Usually the issue comes if PXA area is too high check abap/buffer size and reduce if needed , compare with DEV/QA the values, hope it will help.
Regards,
Nibu Antony
Kavitha,
Hope the Note 425207 - SAP memory management, current parameter ranges can help you to make decisions on values. Also you can search notes like Note 923610 - Memory parameter recommendations for banking systems for your scenario . Refer https://scn.sap.com/blogs/tyronemapp/2012/05/11/how-to-fix-pxanosharedmemory-short-dump-error-in-sap... to make changes on above said profile parameter .

Hi Nibu,
Your replied are very helpful. Now I am getting another dump in production only. (Dev, QA and prod are all different in config and also in usage and physical memory.) One of the batch job terminated due to this dump. Could you please help me with this one. I have already reduced abap/buffersize as per your earlier suggestion. (this weekend I will restart). In the meantime getting below dump.
Runtime Errors TSV_TNEW_BLOCKS_NO_ROLL_MEMORY
Date and Time 06/12/2013 00:28:33
Short text
No roll storage space of length 2517000 available for internal storage.
What happened?
Each transaction requires some main memory space to process
application data. If the operating system cannot provide any more
space, the transaction is terminated.
What can you do?
Try to find out (e.g. by targetted data selection) whether the
transaction will run with less main memory.
If there is a temporary bottleneck, execute the transaction again.
-
If the error persists, ask your system administrator to check the
following profile parameters:
o ztta/roll_area (1.000.000 - 15.000.000)
Classic roll area per user and internal mode
usual amount of roll area per user and internal mode
o ztta/roll_extension (10.000.000 - 500.000.000)
Amount of memory per user in extended memory (EM)
o abap/heap_area_total (100.000.000 - 1.500.000.000)
Amount of memory (malloc) for all users of an application
server. If several background processes are running on
one server, temporary bottlenecks may occur.
Of course, the amount of memory (in bytes) must also be
available on the machine (main memory or file system swap).
Caution:
The operating system must be set up so that there is also
enough memory for each process. Usually, the maximum address
space is too small.
Ask your hardware manufacturer or your competence center
about this.
In this case, consult your hardware vendor
abap/heap_area_dia: (10.000.000 - 1.000.000.000)
Restriction of memory allocated to the heap with malloc
for each dialog process.
Parameters for background processes:
abap/heap_area_nondia: (10.000.000 - 1.000.000.000)
Restriction of memory allocated to the heap with malloc
for each background process.
Other memory-relevant parameters are:
em/initial_size_MB: (35-1200)
Extended memory area from which all users of an
application server can satisfy their memory requirement.
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
.
You can use the ABAP dump analysis transaction ST22 to view and manage
termination messages, in particular for long term reference.
Error analysis
The internal table "\FUNCTION-POOL=STXC\DATA=OTF[]" could not be enlarged
further.
Memory location: "Session memory"
You attempted to extend the data structure for the management of the
memory blocks for table "\FUNCTION-POOL=STXC\DATA=OTF[]". However, the 2517000
bytes required for
this were no longer available in the specified memory area.
The amount of memory requested is no longer available.
How to correct the error
Try to decide by analysis whether this request is
reasonable or whether there is a program error. You should pay
particular attention to the internal table entries listed below.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"TSV_TNEW_BLOCKS_NO_ROLL_MEMORY" " "
"SAPLSTXC" or "LSTXCOTF"
"OTF_APPEND"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.
