[Freeswitch-users] FreeSWITCH dying with no core file

[Adam Johnston]

Andrew,

I loaded the core file into gdb and looked at the backtrace. It turns out
that the problem was not in the FreeSWITCH code but rather in LuaSocket,
and the error was thrown while I was caching fax results in a key-value
store using a Lua script. My issue was very similar to this Jira:
http://jira.freeswitch.org/browse/FS-2893. I recompiled LuaSocket with the
FreeSWITCH includes and am hoping that fixes things.
