[Freeswitch-users] FS freeze with 100% CPU rate frequently

Tue Dec 15 02:24:19 MSK 2015

I don't know if this is on the wiki or not but I have detailed this process
many times if you really want to know what is causing it.

1) Save the output from this command:

top -b -H -p `cat /usr/local/freeswitch/run/freeswitch.pid` -n 1

2) get a gcore:

gcore `cat /usr/local/freeswitch/run/freeswitch.pid`

open the corefile in gdb, do "info threads" find the pid that matches the
thread that is 100%cpu

switch to that thread by the number gdb assigned to it (e.g. thread 12)

get a bt... as usual with a crash......
