[Freeswitch-users] 100% CPU usage

[Grant Bagdasarian]

Hi Antony and Antonio,

Thank you for the tips.
We haven’t had freeswitch going berserk anymore (not sure as to why it did perform without issue over the weekend), but will continue to monitor it and run the commands to trace the issue.

Regards,

Grant

Make sure you lua script has all while loops including session:ready() as a condition to continue.  Its a common mistake that leads to loops spinning out of control on hungup channels.

Hi,

You can use the following commands:

#get a core:

gcore -o /home/gcore-$(date +%s) $(cat /var/run/freeswitch/freeswitch.pid)





#check thread usage:

top -p $(cat /var/run/freeswitch/freeswitch.pid) -H -b -n 1





#memory mapping:

cat /proc/$(cat /var/run/freeswitch/freeswitch.pid)/maps


you can get some info from fs:

fs_cli -x "sofia global siptrace on"

fs_cli -x "fsctl debug_level 10"

fs_cli -x "sofia loglevel all 9"

fs_cli -x "fsctl debug_sql "

fs_cli -x "sofia global debug presence"


Put everything into a jira so we can take a look.


Regards,
António

Hi,

We’re currently experiencing a weird issue with one of our freeswitch servers where the CPU just goes berserk and stays at 100%.
There are no active calls at that moment, but FS is still using 100% CPU.

I was unable to get a debug using gdb, since freeswitch does not crash.

We had this issue on 1.6.13 and then I upgraded to 1.6.15 this morning, but the problem still persists.
There is currently only one active application running on this box which is using LUA. Maybe that is causing the issue?
We checked the code but there are no weird loops etc. Perhaps we are missing something?

Any ideas how to trace this?

Regards,

Grant
