Bug#471460: asterisk: 100% CPU usage spikes

Package: asterisk
Version: 1:1.4.17~dfsg-2+b1
Severity: important


Hi

I recenlty upgraded my asterisk system from etch to lenny and I am now experiencing
a problem where the system will periodically hang for a few seconds then recover.
I can't see anything unusual from the CLI, all that happens is asterisk will randomly
start to comsume 100% of the CPU and after around 10 seconds will return to normal.
When it happens I usually see a number of "peer unreachable" messages, but that's about it.
I am running out of time to debug this as my users need a stable system so I should really
be reverting back to etch, but if there is anything I can do to debug this in the next day or so,
let me know what to do and I will try it.

Thanks
