Asterisk concuming 400% of the CPU

[fadihadd]

Hello,

I have a serious problem with my asterisk server, sometimes its consuming 400 % of the CPU since I have 4 Cores ... Im trying to find what is the root cause of this issue with no luck.
I searched a lot for this problem and I found what the exact thread that consuming the CPU usage which is PBX_Thread ... I think this is the main one.

Check the below:

Thread 4 (Thread 0x40dda940 (LWP 5539)):
#0 0x00002ad3725f4ab6 in poll () from /lib64/libc.so.6

#8 0x00002ad3725fd9ad in clone () from /lib64/libc.so.6

Any ideas guys?

Any wierd error messages in the CLI ? I've seen bad USB ports or NIC interfaces cause lots of error messages and that drive up CPU use. Did you look at the syslogd to see if any errors or the Asterisk log files during these peak cpu use times ?
