Hello,

can you enable pkg summary and generate it once the out of memory happens?

Set memlog to lower value than debug, when the memory happens, do:

https://www.kamailio.org/docs/modules/devel/modules/corex.html#corex.rpc.pkg_summary

Then send some traffic to that process and watch the syslog.

Alternative, enable memory summary via core parameter and stop kamailio when the errors happen, but you will get summary for all processes, so it might be harder to extract those log messages related the evapi process.

Cheers,
Daniel

Hello there,

I'm using kamailio 5.2.1 with evapi module to send and receive events from an external application.

 

During my stress tests to kamailio i have been noticing that at some point kamailio is getting out of memory:

edge-sip-proxy[20565]ERROR: ESP_LOG: <null>: <core> [core/mem/q_malloc.c:291]: qm_find_free(): qm_find_free(0x7fb8730b6010, 64); Free fragment not found!

edge-sip-proxy[20565]: ERROR: ESP_LOG: <null>: <core> [core/mem/q_malloc.c:425]: qm_malloc(): qm_malloc(0x7fb8730b6010, 64) called from core: core/parser/msg_parser.c: parse_headers(325), module: core; Free fragment not found!

edge-sip-proxy[20565]: ERROR: ESP_LOG: <null>: <core> [core/parser/msg_parser.c:328]: parse_headers(): memory allocation error

edge-sip-proxy[20565]: ERROR: ESP_LOG: <null>: pv [pv_core.c:704]: pv_get_callid(): cannot parse Call-Id header

edge-sip-proxy[20565]: INFO: ESP_LOG: <null>: [evapi:connection-received] EVAPI msg received -> {"aor":"sip:FUZECI1-x1516@uc.fuze.domain","contact":"<sip:FUZECI1-x1516@10.225.121.206:5060;transport=UDP>"}

edge-sip-proxy[20565]: ERROR: ESP_LOG: <null>: <core> [core/mem/q_malloc.c:291]: qm_find_free(): qm_find_free(0x7fb8730b6010, 64); Free fragment not found!

The process id 20565 is running out of memory as you can see bellow:

output of kamcmd pkg.stats 

entry: 14

pid: 

rank: -2

used: 6058696

free: 824

real_used: 8387784

total_size: 8388608

total_frags: 30

This process ID is related with Evapi Dispatcher

kamcmd ps | grep 20565

20565 EvAPI Dispatcher

After stop the sipp that was generating traffic to kamailio the evapi process still have all the memory consumed

Can it be some memory leak in Evapi module?

Best Regards
