Hi Brian,

Not for today, the first time it happens was my first though something with the traffic, but i couldn't find any association with the type of traffic. Actually after restart fs i receive traffic from the same endpoints, same type of calls and the issue don't reproduce until next morning...

There was something i was doing at 00 every day, the command "fsctl sync_clock"... well i just disabled it today. I've to wait until tomorrow to check the results. 

I just install fs compiled with tcmalloc, so if there is no problems i will put back the "sync_clock " command to really check if it could be the cause.

Right now i'm quite lost on what to do more...

Do you have pcaps of the traffic that may trigger this behavior?

Antonio, you should install this:

apt-get install libgoogle-perftools-dev

Try this: ./configure LIBS="-ltcmalloc"

Hi,

Did you compile fs in debian with tcmalloc?

didn't work for me... do i miss something?

Hi Juan,

Thanks for the tips!!

Unfortunately i cannot test with -nosql option, i need to have the sip_registration fill to be able to send options to natted endpoints. But i don't think the issue is in db, i use postgres and to get better performance from it i run it on tmpfs.


I read about tcmalloc, but from jira FS-7315, i get the idea that it didn't change anything.. but i guess i can try it and post the results, from the bt i do see some calls been done to malloc, but not sure if they are locking or not.

Regards,

Hello Antonio,

I had the same issue, to fix it i tried many things written in this mail list. Try running FS with -nosql option, if that doesn't work recompile FS with tcmalloc (from google's perfomance tools).

That did it for me.

Regards,

Juan Pablo.

Hi,

i'm having an issue with FS that gets lock every morning  with cpu sys
hitting 80%, because is limited in fs with min-idle, it could reach the
100%, so the calls are rejected by load, to solve the problem i kill fs
and start it again.

I discard a load issue, because after restarting freeswitch the system
increases in number of sessions/cps and no problems at all until next
day.... it's given me crazy... i've enough memory, lots of cores...
after restart fs the system stays at less than 30% of cpu usage.


Right now i have hpet as clocksource, transcoding is minimal (use
inheric_codec, only happens because of different ptimes with some
endpoints) .


anyone having similar problem? or any tip i can do to debug this issue?


For info the Jira ticket can be located at
https://freeswitch.org/jira/browse/FS-9957,

i've done a gcore, top, htop when the system is with high cpu sys but i
can't figure the thread that is causing the issue... initial i thought
it was because of module lua (most of my logic is done there), but today
only 2 threads where running mod_lua when it happen.


Appreciate the help.
