mysterious wedges in bind9

My primary bind9 name server which does double-duty as a server and recursive lookup
is becoming "wedged" where it does not respond to queries or stop events from rndc.
Sending SIGTERM does not work; I have to SIGKILL (kill -9) it.

Package info:
ii  bind9                 1:9.5.0.dfsg.P2-1ubun Internet Domain Name Server

Ubuntu 8.10

Needless to say, this is causing me a headache.  When it's down, SSH operations
take over a minute.

Strangely, I have an identical server which slaves all the same domains but does
not ever exhibit this behavior.

What can/should I do to troubleshoot this?

Thanks in advance!
