Subject: [asterisk-users] Asterisk 1.62.13 - CPU spikes every 10 minutes

 

Hi,

 

I've been getting regular CPU usage spikes(50%-80%), due to asterisk
(according to top).  I never noticed this on 1.4, and I have top running in
the background pretty much all the time. In between those spikes Asterisk
stays under 10% CPU usage (I have a transcoder card, which helps).

 

It's very regular, never any missed spike, or any spike in between the
regular spikes.  I don`t have cron job running every 10 minutes
(asterisk-related or not).

 

Because it's so regular, I don`t think it's anything in my dialplan.  If it
was it would be more random. SIP peers are reregistering every 60 seconds,
so the spikes would be every minute if that was the problem.  There is no
"scheduled" attack from outside that I know of, network traffic (calculated
from the switch port and the server) does NOT spike. Memory is very stable
at a low value.

 

Does anyone have an idea of where to start looking? Can Asterisk report
somehow what is causing this?

 

Mike

 

I would start with /var/log/asterisk/messages and /var/log/asterisk/full to
see what is (was) happening (if anything) on the console at these spike
times.
