[Freeswitch-users] Freeswitch 1.4.15 and a sudden jump in CPU usage

Wed Feb 11 17:03:49 MSK 2015

Dear Muhammad,

I think your issue is different than Ali Pey because CPU rises at a
specific time (approx) while running fine most of the time. In my
experience you should check following ..
- Check using top commands if its indeed freeswitch taking up CPU. It may
be logrotate or something.
- If you are using DB on same server, also check DB connections, May be
some long running query causing it (Like someone fires some billing report
at approx same time)

On the other hand when you say "it runs fine all day". You may want to
check that using top command at different time of day, may be CPU usage
keep on increasing and in your peak time it increases so much that you see
symptoms. (If this is true may be you and Ali pey have same issue perhaps
some CPU leak).

P.S. All points I mentioned are from my VOIP experiences in general. I am
NOT freeswitch expert. I have recently started experiments with freeswitch
so people who are using freeswitch or experts will give more meaningful
insight.
