Freeswitch Segfaults

8 Nov 2013

      Hi everyone,

We've been having some server crashes lately.  We thought our most recent upgrade had fixed it, but unfortunately, it crashed again the other day.  Based on the information below, does anyone have any recommendations or thoughts?  Always seems to segfault.

We are connected to it via RTMP from a Flash Media Server if that helps at all.
