asterisk users - Feb 2007 - asterisk freeze due to "too many open file" error

Hi,
my Asterisk 1.2.9.1 suddenly freezed ("stop now" did not work!!) . I 
found the following errors inside /var/log/asterisk/message:

Feb 14 14:55:41 ERROR[11273] rtp.c: Unable to allocate socket: Too many

Considered that the result of ulimit is "ulimited", is there anybody
who
knows how to avoid these errors?

TIA

Could you kill the asterisk process directly?

we have this problem. In our case it was due to the voice mail app; it 
was failing to unlink files in memory when creating mp3s. Not sure what 
your specific problem might be

- is it opening a file and never closing it again, etc. Hard to track
down unless you have a good knowlege of what's running, etc.

lsof -p `ps h -C asterisk -o pid | head -1` | grep -Fc '/dev/zap/timer'

120

You have to open your own timer device over one hundred times in the same
process?
