[OpenSIPS-Users] opensips crash when doing load test

Fri Sep 30 15:44:19 CEST 2016

Hi Bogdan,

I have taken 2.1.4 code base, added the below fixes on top of it

1.       Fix potential starvation for the timer tasks. 66c337cc89a2b5c3e1bbd78c289371efcda21886

2.       rest_client: Improve polling logic during TCP connect - c40f2b057209b8078520abc95e5d1bf5e5a28db6

3.       rest_client: Add "connect_poll_interval" module parameter - f5abfb3dee649a14ae39ad74d7f04454f815748f

4.       rest_client: Fix bogus condition -3ba7be6692c6987faecb9c4c904035d5e7c0f916

When I try to perform load test on that code base, randomly am seeing OpenSIPS is crashing.
Here is the full trace of the core file. Let me know if you need any additional information or logs.
Am seeing crash is occurring at start_timer_extra_processes().
