When using FQDN node/pool member resolution, a non-primary bigd process may core under certain circumstances. A non-primary bigd is any process instance other than zero in a multi-bigd scenario, or any bigd process on a non-primary blade in a chassis.
bigd may core and be restarted in a loop, causing some monitor instances to not be serviced. This may cause node/pool member flapping, or may cause certain nodes or pool members to be effectively not monitored.
FQDN is in use.
Use static IPs instead of FQDN for node/pool member address assignment.
Known causes of the bug have been fixed.
