Hi, On 64 bit centos 5.6 I have virtualbox 4 and 64 bit elastix latest. Since yesterday cpu utilization has been constantly peaking 65-75%. Hardly 1-2 concurrent calls. No other activity on server. Top shows asterisk on top. Its quad xeon server with 4 gb ram. Any suggestion where should I start and how should I go about with my investigation. Thank you and have a great weekend.

Sorry fro hijacking thread. I have following process running on my asterisk eating around 2 or 3% CPU constantly. I knew events0/1 is CPU queue but why only single queue is busy ? I have kernel running preemtive with 1000Hz satish at campbx1:~$ ps aux | grep events root 9 1.7 0.0 0 0 ? S May08 201:35 [events/0] root 10 0.0 0.0 0 0 ?

First grab LWP thread ID which is eating more CPU
ps -LlFm -p `pidof asterisk`
Now look into your asterisk.stack.txt and search particular LWP thread ID see
following example
Thread 10 (Thread 0x41d8f940 (LWP 3406)):
#0 0x00000033ce2ca436 in poll () from /lib64/libc.so.6
#1 0x00000000004933c0 in ast_io_wait ()
#2 0x00002aaabd9510cd in network_thread ()
#3 0x00000000004f8b2c in dummy_start ()
#4 0x00000033cee06367 in start_thread () from /lib64/libpthread.so.0
#5 0x00000033ce2d2f7d in clone () from /lib64/libc.so.6
Now you have piece of cake. whatever the issue is you can find in above few
lines..

http://www.moythreads.com/wordpress/2009/05/06/why-does-asterisk-consume-100-cpu/
Moving forward with the suggestion provided on the above link, I have the
activity dump of all asterisk processes when the load was 22%.
Need help in understanding the output.
What should I look for which would indicate undue CPU utilization.
Any finding in my asterisk.stack.txt ?
Thank you.

With just 3 concurrent calls and none in queue, the CPU is constantly above 40%.
The moment CPU goes above 50%, calls start to break.
