Experienced some slowness on a MailScanner machine running bind 9.2.1 
today & noticed this in the logs:

Dec 19 14:10:12 mailfilter named[790]: task.c:395: REQUIRE((((task) != 
((void *)0)) && (((const isc__magic_t *)(task))->magic == ((d

Dec 19 14:10:12 mailfilter named[790]: exiting (due to assertion failure)

  It restarted fine.
Any advise?
Thanks,
