Opened: Feb 11, 2016
Severity: 3-Major

Symptoms

If an FQDN pool member has been disabled by a monitor (for example, after the monitor receives the configured recv-disable string from the node) and the monitor is then removed from the pool or member configuration, the FQDN pool member remains in a 'disabled' state (state and session-status are 'disabled') instead of changing to an 'unknown' state.

Impact

The FQDN pool member remains in a 'disabled' state and is unable to receive traffic.

Conditions

-- FQDN pool member is marked 'disabled' by a monitor. -- The monitor is then removed.

Workaround

There is no workaround at this time.

Fix Information

When an FQDN pool member is marked 'disabled' by a monitor, then the monitor is removed, the FQDN pool member is updated to an 'unknown' state. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.
