[Freeswitch-users] Different behavior of FS under gdb

[mayamatakeshi]

I tried using gcore but it got frozen too (and now I realize FS is
consuming 95% of the CPU time so probably it entered an infinite loop).
But i can see gcore is just a wrapper for gdb so I can check its man page
and try other things.
Thanks for the tip.
