[OpenSIPS-Devel] [opensips] OpenSIPS 2.1 Crash (#732)

Thu Jan 14 10:02:01 CET 2016

I have updated opensips to v2.1.1 Git Rev. 4c775f2. I still have crash through frequency is a bit reduced now, previously it was crashing on every call, now it crashes every 2nd or 3rd call. I see two core dumps, here are their back traces.
