Summary:                    [patch] Asterisk hangs with no calls being able to
go in or out, and the console does not respond to commands
Description: 
I'm not sure if we are seeing one or two different issues.

We've had stability issues with all versions of 1.8 we've tried. Those
include 1.8rc2, 1.8 final,a trunk checkout some weeks after 1.8 final and
latest 1.8.2rc1 all had the same issue or similar issues (They all
froze/crashed)

So far i do not have any type of debug information to show, but im
counting on being able to get some next time it happens. It's so far
happened about once every 6-9 days, and strangely enough it typically
doesnt happen for over a week and then happens 2-3 times on the same day.
