[SR-Users] Out of Memory Error in Kamailio

Hi Guys,
I am using Kamailio-4.2.1. Earlier I was using shared memory of 16GB, which
started popping out of memory error, within few seconds of generating load
from sipp.
I used sipp following command:
sipp -s 999999999999 MY_KAM_IP -l 2500 -r 50
*Error coming is :*
*Feb 4 14:12:23 kamailio_us_ha1 /usr/local/sbin/kamailio[27389]: ERROR: tm
[t_reply.c:1946]: relay_reply(): ERROR: relay_reply: cannot alloc reply
shmem*
After changing the shared memory to 1 GB, this error came quite late when
generate load at 200 CPS.
sipp -s 999999999999MY_KAM_IP -l 2500 -r 200
Why this is happening?
I am using following configuration file( kamailio.cfg). Earliest possible
help will be appreciated a lot!!
