Can't trace source of free 'resource' error in syslog. Bind-9.2

[Robert]

FreeBSD. 4.5-RC
Bind-9.2
512Mb RAM
1GB Pentium.

This message only appears when certain other applications are running, so
it's very hard to know what is causing it.
I've searched the lists, the web, the archive and all manner of places - but
come up only with my own message..

Doing a grep on the syslog, I find these.

They only appear when Bind-9xxx is running. Bind-8 versions don't do it.

When I start the program Shoutcast, to stream audio (Internet Radio) the
messages start to appear.
When I stop the program, the messages disappear.

Does anyone have any idea why 9.2 is diong this? What is it telling me -
apart from the message itself. I have the kernel set to allow probably
enough resources to handle a major service - yet only 9.2 produces this
message.

Thanks for any ideas
