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 Rahul Gupta From: users-boun...@lists.opensips.org [mailto:users-boun...@lists.opensips.org] On Behalf Of Vlad Paiu Sent: Friday, September 04, 2015 11:59 AM To: users@lists.opensips.org Subject: Re: [OpenSIPS-Users] core generated by opensips 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.

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 ) ?
