Hi All,

We recently upgraded kernel on our ECC6.0 DEV system to 700 Sup.Pkg lvl. 254,

After Upgraded we got some dump in system SYSTEM_CORE_DUMPED :

Short text

Process terminated by signal " ".

What happened?

Error in the SAP kernel.

The current ABAP "SAPMSSY30" program had to be terminated because the

ABAP processor detected an internal system error.

Last error logged in SAP kernel

Component............ "Taskhandler"

Place................ "SAP-Server host name(wp 8)"

Version.............. 1

Error code........... 11

Error text........... "ThSigHandler: signal"

Description.......... " "

System call.......... " "

Module............... "thxxhead.c"

Line................. 10852

The error reported by the operating system is:

Error number..... " "

Error text....... " "

How to correct the error

The R/3 System work directory (e.g. /usr/sap/c11/D00/work ) often

contains a file called 'core'.

Information on where terminated

Termination occurred in the ABAP program "SAPMSSY30" - in "SYSTEM-EXIT".

The main program was "SAPMSSY30 ".

In the source code you have the termination point in line 0

of the (Include) program " ".

Internal notes

The termination was triggered in function "ab_CoreInfo"

of the SAP kernel, in line 7371 of the module


The internal operation just processed is " ".

Internal mode was started at 20101207075643.

Stack trace of 'core'.

After 4,5 dumps we are not getting this dump but we are trying to find out root cause of this dump.

Please suggest so that we can stop this dump to generate in QAS system after kernel Upgrade.

    Hi ,

    Please take a look at note 1121904 for some details. When the systen isrunning short of memory and also the paging space is getting full, a signal 33 is sent to all processes in the system. Processes can react on

    this signal to free up memory.

    If not enough memory is releseased, the oprating system is starting

    to stop processes ( and with this freeing up memory ) to ensure

    correct that the OS still can run.

    you can get the log from dev_w0 ,dev_W1,etc ...

    Any specific program or tcode you are getting this dump?

    Have you upgraded the kernel on DEV as well, any issues?

    As you told that this has been reported after kernel upgrade then you better try to check for those system which is on old kernel.. also this dump is only "REQUEST" specific which is generated only due to specific function ex- this will never generate while running SM50, what I mean check with user what task is generating this dump and after you notice that this is due to new kernel upgrade then better open up SAP message.

    - open ST22

    - click on the left side on "analysis section" (bottom)

    - post the stack trace

      You sure that you are on 254? As per note the parameter rdisp/ss_enforce_rollout is not required to set if you are on 7.00: 193 patch.
