Hi,
We are constantly encountering the TSV_TNEW_BLOCKS_NO_ROLL_MEMORY dump in our production system.
Following are the memory parameters :
System : SAP PRD (One instance )(ABAP system)
Kernel :700
AIX : 6.1
em/initial_size_MB =4092 MB
PHYS_MEMSIZE = 25GB
em/max_size_MB= 4092 MB
em/address_space_MB = 4092 MB
em/global_area_MB = 250
em/total_size_MB = 16384
apab/heap_area_dia = 2000000000
abap/heap_area_nondia = 2000000000
abap/heap_area_total = 4000000000
ztta/roll_area = 6500000
ztta/roll_first = 1
ztta/roll_extension = 2000000000
rdisp/ROLL_MAXFS = 32768
rdisp/roll_SHM = 16384
rdisp/PG_MAXFS = 32768
rdisp/PG_SHM = 8192
RAM and other hardware specifications :
prdsap1:p01adm 6> lsattr -El mem0 -a size

Kindly suggest the requisite changes which are needed to be done in terms of memory parameters .
I have attached the st22 dump.
