asterisk users - Mar 2012 - asterisk 1.8.9.2 channel.c: Channel allocation failed

Hello List!

My Asterisk stopped making SIP-calls today, I could call from external, and
saw Call coming in over PRI, but calling the SIP/Device
wont work. I saw 5 open channels - all chan_spy. Only a restart helped.

In the messages-file i found from yesterday:

I'm not sure what's going wrong? My ulimit should by unlimited.

The log messages seem quite clear what the problem is: you ran out of 
available file descriptors. It even mentions what you should do and what 
the command is: raise the amount of available file descriptors with 
ulimit -n.
