[Asterisk-Users] Asterisk causing server to hang ... any hints?

Tue Feb 8 16:53:37 MST 2005

If the asterisk process is hung up you should be able to debug it. If
the whole machine is hung up this is a totally different issue isn't it.
If you're running linux and the machine locks up that often, you must
have a hardware problem. Or maybe you just think the machine is locked
up while it actually isn't. 

You might want to look on google and the wiki about deadlocks, I've seen
a lot of information around on how to debug them and report them.
