So we have 20 queues with --file-count=64 option and 25 queues with

According to the formula nfh=nq * (nf + 1) to estimate the number of file
handles from the following link http://www.redhat.com/f/pdf/Large_Journal.pdf
nfh=20 * (64 + 1) + 25 * (8 + 1) = 1525
But the maximum number of the open files for qpid is set to 16384 that is ten
times greater.
What about connections (qpid-stat -c), how many of those do you expect
to have?
Are the queues fairly static (i.e. the queues themselves don't really
change, just the messages on them)? I guess it is also possible there is
some sort of leak of handles(?)...
If you could monitor the open file handles during operation (or testing)
and observe any patterns that may also help.
