This is the system-wide limit on open files (seems a bit low for a
server).  The user limit can be seen with a 'ulimit -n' and can be set
higher with a 'ulimit -n 4096' style command, as root, to work around
this problem.  I would suggest a doubling of the current ulimit.  If the
system limit is being reached somehow, then look here:

or if that wraps:

I'm going to need to chase this one some more it looks like.  I thought
it was fixed.
