[asterisk-users] Asterisk-cpu utilization > 60 %

[satish patel]

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..

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.
