[Asterisk-Users] Sip too many open files?

[Brancaleoni Matteo]

Today my pbx stopped responding to my sip phones..
looking into the log, here what I got:

Also wasn't possible to connect via a unix console...
And so on... until I restarted the asterisk proc.
What can cause that?
I'm running CVS-06/22/03-16:32:23 , on a p4 2.4ghz
and 512 mb ram, kern 2.4.21

Thanks a lot,
Matteo
