Asterisk using a lot of CPU

Asterisk Asterisk Support
1

Hi all,

i have a Pentium IV 3.6Ghz HT CPU with 512Mb Dual channel Ram with Mandrake 10.1 with kernel 2.6.11-6mdksmp
im running asterisk zaptel and libpri 1.0.9.

The asterisk is using 99.9% CPU with 4 or 5 calls from sip/IAX2 to a ZAP channel.

anyone knows what is the problem?

There is the process tree of asterisk

Check if you don’t have a music on hold process that ran away. Look for the process “mpg123” under processes in the System Monitor. You will probably find that it is using 60-70% of the cpu. It won’t be the mpg123 process under the Asterisk branch but it will occur on it’s own in System Monitor.

Make sure you have %CPU selected in the System Monitor options to see that.
