[OpenSIPS-Users] core generated by opensips

Hi Vlad, thanks for debugging the issue on our server, I appreciate your valuable time. I have enabled memory debugging and waiting for the issue to happen.

Meanwhile I have uploaded the gdb traces for the deadlock issue which caused 100% cps you have looked at another server. The link to github issue is github:  https://github.com/OpenSIPS/opensips/issues/630

Thanks

Hello,

As per our meeting today, please enable memory debugging on your server, and let me know when another crash happens, so I can take a look at the newly generated core file.

Regards,

Hello,

Can you replicate the crash on demand, or does it happen randomly ?
Would you be able to provide access to a server containing the core file and the OpenSIPS binary, in order to speed-up the debugging process ( avoid the ping pong on the mailing list ) ?
