There are many named Post queues and some or all of them core dump with the message “shs_realloc_stat” appearing as below in the file core.out located in the same directory as the core file:
----------------- lwp# 1 / thread# 1 --------------------
ffffffd9ff093668 si_alloc_stat (1e, 30305302, 0, f0, 5dc, 0) + 5c
ffffffd9ff095fa0 shs_realloc_stat (30305302, 5dc, 1002261a0, ffffffd9ff266678, 1000be140, ffffffd9f9f4a300) + e0
0000000100089b64 SessAllocStats (579, 0, 0, fffffffffffffff8, 0, 0) + 3ec
The setting of the parameter SP_SHS_SHMSIZE is inadequate to handle the number of Post queues.
Use trial and error and progressively increase the parameter SP_SHS_SHMSIZE value from 16M to 32M, 64M, or 128M to see if this resolves the Post core dump issue. Every time the value is changed, Shareplex will need to be bounced for the change to take effect and then the value may have to be upped again if the earlier increase does not help.
For example, to increase it to 32M:
sp_ctrl>set param SP_SHS_SHMSIZE 33554432
sp_ctrl>shutdown
Then restart Shareplex to see if this helps and if it does not, try further increases.
