Summary:                    SIP channel stops processing calls, but no apparent
deadlock
Description: 
Approximately once per week we are seeing asterisk stop processing SIP
calls. The behavior is the same as a deadlock, but core show locks does not
show any evidence that there is a deadlock. 

The only way to resolve is to restart asterisk. 

output of:
core show locks
info thread
thread apply all bt

from the running process is attached.

Guys, something new(at least for me) here.

We got a lock a couple minutes ago.

Looking into the log full I got a lot of "Too many open files" messages.
Im not sure if it is after or before the lock. Could it be the cause for
the lock? 

My ulimit -n show me 1024.

lsof on asterisk thread show me a lot of more than 1024.

I just increased this number to  ulimit -n 65355.

How it sounds for you?

callguy: Could you post your ulimit -a values? Im running an Etch Debian.
