After observing this for some days now (with no progress towards a
solution), i think this might be a problem with the kernel rather than
BIND. I have a 5.2.1-p5 system that shows the same symptons. It is
lightly loaded and the above mentioned symptons start appearing after
1-3 days of uptime. A restart of BIND does not change anything, but af
reboot of the system gives me another few days of correct operation.

I hope the above can give someone more hints to what might be going on.
I also hope to get some pointers to resource counters i can check to try
an identify if something is leaking.

The mail system is standard qmail, qmail-scanner with clamav and
spamassassin and vpopmail - all from ports.

Thanks for any hints or information in advance,
