Stopping named core dumps on HPUX 11.0

[Jay W. Reffner]

I've got 2 BIND 9.1.0 servers running on 2 HPUX 11 systems.  One primary 
and one secondary.  My secondary server is fine, no problems.  When I 
stop named on my primary server, it core dumps every time.  The named 
process terminates and the following gets written to the syslog:

Feb 19 09:17:10 packy /usr/sbin/named[858]: shutting down
Feb 19 09:17:12 packy /usr/sbin/named[858]: no longer listening on 
xxx.xxx.xxx.xxx#53
Feb 19 09:17:12 packy /usr/sbin/named[858]: no longer listening on 
127.0.0.1#53
Feb 19 09:17:21 packy /usr/sbin/named[858]: mem.c:1404: 
REQUIRE(mpctx->allocated == 0) failed
Feb 19 09:17:21 packy /usr/sbin/named[858]: exiting (due to assertion 
failure)

Afterwards, I restart the service and it runs fine again until I try to 
shut it down...giving me yet another core.  named doesn't crash 
unexpectedly, only on exit.  Any help would be greatly appreciated.

Sincerely,
