[SR-Users] S-CSCF can not allocate memory

[tyd]

Hello,

I haved install debian 8 and kamailio 4.4.7 for IMS testing.
After registering 10000 users, SIPp generates CPS 25 SIP INVITE message and
BYE message after 100 seconds.
After about 240000 calls, there are "cannot allocate memory" messgae on
S-CSCF.
The command of S-CSCF is "kamailio -m 512 -f /etc/scscf/kamailio.cfg"
The parameter mem_join=1 is included in kamailio.cfg.
I have modified the share memory to 1024 and 2048, but the result is the
same, just increasing the pass calls.


Would you please tell me how to solve the memory problem?
Thanks.
