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?

Regards,
Ricardo.

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