Problem with BIND 9.2.1

Dear Sir,

I have installed RedHat 9.0 on my computer which act as a server.
However, when I install and configure BIND to act as a DNS server, all the
configuration are fine (I have use this piece of information in another
RedHat 9.0 machine). I can resolve domain in internet and solve my domain
too. However, when I try to stop/restart named, it fails. The error
messages are as follow:

Sep 30 13:06:15 newton named[702]: app.c:561: unexpected error:
Sep 30 13:06:15 newton named[702]: isc_app_shutdown() pthread_kill: No such process

What's wong? Could anybody help me? Thanks!

Regards,
