Symptoms

Multiple FQDN ephemeral nodes may be created unexpectedly if an FQDN node is configured with autopopulate disabled, the DNS server returns multiple address records for the FQDN, and bigd is restarted.

Impact

Multiple FQDN ephemeral nodes may be created unexpectedly.

Conditions

This may occur when: 1. An FQDN node is configured with autopopulate disabled. 2. The DNS server returns multiple address records for the FQDN. 3. There is a pool configured to use the FQDN node. 4. bigd is restarted (such as when the system goes offline or tmm restarts).

Workaround

Configure the FQDN node with autopopulate enabled.

Fix Information

Multiple FQDN ephemeral nodes are no longer created unexpectedly if an FQDN node is configured with autopopulate disabled, the DNS server returns multiple address records, and bigd is restarted. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.
