asterisk users - Dec 2009 - sip show peers returns several notices

Hello everybody,

When I execute the "sip show peers" command in the asterisk console I
always get the following notice, repeated 15 times after the sip show
peers output.

[Dec 21 03:38:31] NOTICE[12693]: utils.c:1074 ast_wait_for_output:
Timed out trying to write

This happens on a freshly installed 1.6.1.12 and a 1.6.1.6 box that I
am running. Both of them use Debian Linux (lenny) on Dell PowerEdge
1950. My list of SIP peers is quite large (3000+).

I have not noticed anything wrong with the asterisk installation apart
from this notice, but it is worrying as the error seems to crop up in
other bug reports as a precursor to crashes.

Perhaps you are running up against the limit of 1024 open files for a
process (I think that is the default number of allowed open files for a
process). You can execute 'ls -l /proc/{PID}/fd | wc -l' (replacing
{PID} with the process ID of asterisk) to get an estimate of how many
files it has open. I've modified my asterisk init script to modify that
value with ulimit. My system has 192 DAHDI channels and 227 SIP peers.
When a lot of channels are in use, the number of open files climbs.
