too many open files?

[Matt Mankins]

Hi.

I was just looking through my log file and noticed the following errors:

1) Too many open files -- Is there a way to see the number of active  
connections?
2) Danga::Socket undef error.  The line is:   my $fd = fileno($sock);
3) The process was using 100% of CPU and taking up 126MB.  The number  
of active connections was less than 10.  It sits behind LVS which  
checks for connection uptime periodically which is why the high  
connection count.

DJabberd.pm says our $VERSION = '0.81';

Has anyone seen anything like this before?
