In certain conditions, iquery connection information is not properly cleaned up when the iquery connection is closed.
GTMD core dumps, and is restarted. Monitoring is momentarily impacted. DNS traffic disrupted while gtmd restarts.
This can happen if there are many pending monitor requests pending when an iquery connection is torn down, either because of a timeout or an unreachable GTM/LTM.
