Re: [sr-dev] [kamailio] jsonrpc-c notification does not free shm memory (#296)

Thanks, we're trying to serve as large amount as we can on a single kamailio server. Anyway, after some test, I found the problem may related to debug level. If I switch on memdbg, it'll have a HUGE impact to kamailio and cause TCP connection drop. If I leave debug=-2, then it runs well. Normally it should not switch on memlog on a running production server. So I think this issue can be closed now. Again, thank you for all your great contributions, really appreciate your help. ### Further information if anyone interest in Env: ``` start kamailio with pkg 2G, shm 2G sipp with 1000 RPS ``` #### TEST 1: with memdbg on ( lots of logs write to syslog ) It will drop tcp connection along with shm goes down. And sipp will stop and shows `Broken pipe on TCP connection, remote peer probably closed the socket.` #### TEST 2: disable all logs, at log level -2, nearly no logs at all It runs well, and did not keep swallowing shm at this level. free shm 208811808 more or less. ``` root@SIP-B03:~# kamcmd core.shmmem { total: 1073741824 free: 208811808 used: 862058976 real_used: 864930016 max_used: 864952488 fragments: 253 } ``` --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/296#issuecomment-138469916
