<FONT FACE="Monaco, Courier New"><SPAN STYLE='font-size:11pt'>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)...<BR>
<BR>
I would be looking at something like iotop or something else to see where that load is coming from<BR>
<BR>
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... <BR>

</SPAN></FONT><FONT FACE="Monaco, Courier New"><SPAN STYLE='font-size:11pt'>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...<BR>
<BR>
Where did I get the 100+ number? From looking at ‘top’ or ‘w’ on a box to see what the current load avg is...<BR>
<BR>
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...<BR>
<BR>
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.<BR>
Example code for linux such as Centos or Debian assuming freeswitch is installed to /usr/local/freeswitch<BR>
<BR>
Shutdown freeswitch<BR>
rm –rf /usr/local/freeswitch/db/*<BR>
mount –t tmpfs tmpfs /usr/local/freeswitch/db<BR>
Startup freeswitch<BR>
<BR>
Once you have done that stick it back in rotation... <BR>
<BR>
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)<BR>

Hi Ken.<BR>
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?<BR>
Anyway, what is running a sqlite in freeswitch. Does this have to do with the core.db file? Or with the cdr_sqlite module?.<BR>
<BR>
Thanks<BR>

Sqlite does this every so often or if its calling a sync.... <BR>
<BR>
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<BR>

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

Ricardo.<BR>

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