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?

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'?
