INSIST message

[Bischof, Ralph F. (MSFC-IS40)[NICS]]

Hello,

	I have had a couple of INSIST messages in my general log. I am running BIND 9.6-ESV-R4-P3. Can someone enlighten me as to why I would be getting these? Out of over 125 machines, this is the only one that has logged this message starting yesterday. This is a recursive authoritative server. Can I offer any other information to help troubleshoot this?

17-Feb-2012 14:46:40.301 general: task.c:1229: INSIST((((manager->tasks).head == ((void *)0)) ? isc_boolean_true : isc_boolean_false)) failed

Thank you,
