[Freeswitch-users] Strangely High CPU Usage on Idle FS server

[Anthony Minessale]

First get updated to latest before troubleshooting any problems.

If you still have a similar observation lookup how to get a gcore and a
backtrace on the wiki.
Then run:

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

Look for individual pids with high cpu usage.

dump gcore and get a backtrace with info threads, and thread apply all bt.

Use the data to see the thread with the matching pid and report it to jira
http://jira.freeswitch.org


Doing it on the existing older version won't help because we do not
maintain previous minor releases.
