Summary:                    Prodding channel... causes 100% utilization
Description: 
from time to time, asterisk is locked (100% cpu utilization, but not crash)
with "Prodding channel..." messages...
grep "SIP/777-082ae2f8" /var/log/asterisk/messages | wc -l
856979

in my case it happened in entering simple diaplan, calling MoH...
 555 => { Set(TIMEOUT(absolute)=60); MusicOnHold(); }
user is connected over wifi, so maybe some packet was lost in some
critical call stage, that causes sip channel starts looping?

unfortunately, I was not able to do some debugging, because asterisk pc
was completely locked, due to realtime priority of asterisk process...

it seems, that asterisk have some memory leak, 
it starts about 20MB memory, but after several hours with minimal call
processing load (http://bugs.digium.com/view.php?id=18#30 calls) eats >120MB!
this is also indication for
oncomming crash.
I don't see this behaviour before.
