[Freeswitch-dev] Strange bug - 2

Thu Sep 16 04:45:20 PDT 2010

I should note that you are looking for identical stack traces (up to a
certain depth) that are not blocked (eg on a mutex).  If there is a runaway
thread (100% cpu implies this) then it should be visible in the stack
traces.

I assume you tried running with loglevel 7 and there is nothing useful in
the logs?
