open files                      (-n) 1024

The next time it happens, I'll check.  Last time I did lsof and it  
didn't seem too big, but had nothing to compare it with.  I guess I  
should have compared that with 1024, huh?

The Djabberd process has been behaving quite nicely since then, with  
very little resources used. Incidentally, this is a xen guest machine  
and djabberd is running as its own user.

Will post to the list if I find anything definitive.  Thanks for the  
help.
