[Asterisk-Users] RE: Asterisk stops responding

[David C. Troy]

All --

I am starting to see a similar problem which appeared out of nowhere 
yesterday.  SIP registrations begin to fail and 'reload' does nothing from 
console.  I have not been able to identify a specific event that triggers 
it.  Only thing I can see when this condition is happening is many "UNKN" 
format SIP channels sitting dormant.

I am running CVS-09/04/03.  Has anyone identified a firm cause/fix for 
this problem?

Dave
