Re: [Freeswitch-users] CPU Spikes every 20 minutes
Hello Ken.
In fact i have two transcoding cards for this machine. I was able to
gather performance statistics with “dstat”. This is what I have for a
certain period of time (every 5 second), including the moment it reach high
“load average” (14 or 15). I included the interrupts for eth4 and eth5
(83 and 91) which are the PCIe Sangoma Transcoding Cards. I noticed
certain correlation between the “net received” and the interrupts for the
eth4, could this be the cause of the high load average ??? If so?, are
the RTP packets the cause of this?.
What do you think?!
Regards,
Ricardo.-

Keeping in mind that you are using a sangoma transcoder board, that means
you are handling the equivalent of 440 concurrent calls worth of media for
people not using sangoma transcoding hardware (yes theres 4 call legs in
that scenario, 1 from endpoint A to FS, 1 from FS to D100, 1 From D100 back
to FS, 1 from FS back out to the other end point). That doesn’t sound like
that big of a problem... You will have a fair bit of network traffic that
way (the D100 shows up as another network interface as you are probably
aware)...
I would be looking at something like iotop or something else to see where
that load is coming from
Also, you have plenty of CPU free... So there is either a real problem
here, or this is one of those things where the number of threads handling
RTP and SIP are hanging around the run queue long enough to show up in the
load average...

How many concurrent calls are you doing on that box?

Hi Ken.
I mounted the db directory in RAM as you mention, but the “load average”
still is high.

Load Average is the number of threads/processes waiting in the kernel’s run
queue at sample time... Supposedly number of cores is the how much your
load avg can get to before your boxes is exhausted but this isnt exactly
true on modern hardware with highly multi-threaded software like
FreeSWITCH...
Where did I get the 100+ number? From looking at ‘top’ or ‘w’ on a box to
see what the current load avg is...
Sqlite is used all over FreeSWITCH from the coredb to mod_sofia and
everything in between.... When you type ‘show channels’ from fs_cli it
doesn’t query the structures in RAM to show you that output, it pulls it
from the sqlite db...
That being said, you can test quickly to see if sqlite is hammering the
disk at some point by shifting freeswitch/db dir to a ram drive.
Example code for linux such as Centos or Debian assuming freeswitch is
installed to /usr/local/freeswitch
Shutdown freeswitch
rm –rf /usr/local/freeswitch/db/*
mount –t tmpfs tmpfs /usr/local/freeswitch/db
Startup freeswitch
Once you have done that stick it back in rotation...
Note this will not affect anything but voicemail if you have voicemail
running on that box and not using an external DB via mod_voicemail’s DSN
settings you’ll lose the voicemail DB... (I would assume this is not the
case since you are using this primarily as a Transcoder)

Hi Ken.
Maybe that is the problem. I was sure that the “load average” can’t go
more than #cores in your system. In my case I have 8 cores, so a “load
average” of 12 is high from my point of view. Where did you get the number
100 for this parameter?
Anyway, what is running a sqlite in freeswitch. Does this have to do with
the core.db file? Or with the cdr_sqlite module?.
Thanks

Could it be just a normal sqlite running a vacuum?
Sqlite does this every so often or if its calling a sync....
Also freeswitch with a load avg of 12 for a short period of time isnt
anything to really worry about. Due to the number of threads that’s
possible with FS (ie: 1 per call leg) its not unusual to see a box humming
along and the load avg well above 100 in my experience... This is due to
the number of threads waiting in the run queue when it was sampled... Now,
that’s not saying that this is not specifically indicative or a problem but
something else to think about

Do you have anything like Java running that could be doing garbage
collection?
What other processes are running on the machine? Does TOP show which
process is causing the spike?

Hi Gabe.
I'm mean between the spikes there is nothing different as regarding to the
calls... the cps maintains the same.. there are no scripts running or
crontabs running, the simultaneous calls are the same also. So, for some
reason the "load average" start to grow (every 20 or 25 minutes) without
any clear cause.
I have debug with gdb the moment the server is with 12.5 of "load average"
here : http://pastebin.freeswitch.org/20112
Can we detect a problem from here?

What have you done to verify that it happens 'without any reason'?
