[Asterisk-Users] System freeze

[Jonathan Moore]

I had two system freezes this weekend, first time. I just setup Musiconhold. The
kernel panic referenced mpg123. I turned off musiconhold until I could look into
it more.

> SMP
> MMX
> MeetMe

> follow bug 963 and try to get at the heart of what causes it.
