Andrew,<div><br></div><div><div style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">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: <a href="http://jira.freeswitch.org/browse/FS-2893" target="_blank" style="color:rgb(17,85,204)">http://jira.freeswitch.org/browse/FS-2893</a>. I recompiled LuaSocket with the FreeSWITCH includes and am hoping that fixes things.</div>

</div>You need to set /proc/sys/fs/suid_dumpable to a non-zero value (see man 5 proc), to enable core dumping for processes<br>
that switch their UID on startup (such as freeswitch with -u option).<br>
<br>
By default, the freeswitch process will try to put the core file into the CWD (current work directory),<br>
so make sure the UID it is running as can write there (or "cd" into a different directory before starting it).<br>
You might also want to check out man 5 core, for all the other options (e.g. piping core dumps into a custom handler, with core_pattern).<br>
