Hi Danny,

I have seen that you forwarded the error report.

If the events in the event log are erroneous, how come Bind just closes

This happens every few hours.

The last lines in the event log are as follows:
accept: too many open file descriptors 
socket: too many open file descriptors 
socket.c:2220: fatal error: 
select() failed: Socket operation on non-socket 
exiting (due to fatal error in library) 

The system has been running for quite a while prior to the 'upgrade' to
Bind9.2.1. Previously we where running Bind8.2.x.

There are other things running on the machine, such as web server etc.

The name server running on the machine in question, is one of our least
used name servers, hence it was the first to be 'upgraded'.
