[OpenSIPS-Users] opensip Presence server performance

[Jagadeesh]

Hello all.
  I have integrated OpenSips presence server with my IMS network and I'm testing 
performance with OpenSIPS presence server. I got bad results and the request 
handling in OpenSIPS presence server gets failed with "WARNING:core:fm_malloc: 
Not enough free memory, will atempt defragmenation".

I am just spawning SUBSCRIBE @ 9CPS .
After 30000 scenarios the request handling in fails with 
WARNING:core:fm_malloc: Not enough free memory, will atempt defragmenation.

Even I have increased 
#define PKG_MEM_POOL_SIZE 1024*1024*1024 
in config.h 

STARTOPTIONS="-m 1024" in opensipsctlrc also been changed but ,could not able to 
find much change
