[Asterisk-Users] Urgent Help neededt!! Asterisk 1.0.7 CPU
Hi,
I am quite sure it is asterisk as showed in with the top utility. I have
renamed mpg123 to see if this was causing the problem but the cpu spikes keep
going to 99%....
Asterisk perform well with 1 or 2 calls (with mpg123 and without mpg123) but
when more than 3-4 calls are simultaneous, the load goes to 99% and audio is
bad.
I have noticed 2 asterisk processes at some time with the top utility.
Regards.

Hi,
Are you sure the process consuming your CPU is Asterisk?
Did you tried with different codecs?

[Asterisk-Users] Urgent Help neededt!! Asterisk 1.0.7 CPU
Hi Sebas,
Thanks for your answer. I am including my fstab configuration below and 3
outputs from top showing the asterisk processes eating 99% of cpu, some
times there are 3 or 4 processes, some times there are 2 and some times
there is one which eats 99%.
The 99% of cpu is not all the time, if no calls are being handled by
asterisk, the load is almost 0%, with 1 or 2 calls, some times it is 2-5%,
some times it spikes to 30%,50%,70% or 80%, with more than 3, it becomes
very unstable going up and down.
Any thoughts on this are welcome, we have this system in production at the
customer site and need to solve this as fast as we can.
Your help is valuable.
Regards.

Can you post your "/etc/fstab" ??? and the output for the
"top" command.
