When FQDN nodes and pool members are used in LTM pools, a message similar to the following may be logged if the DNS server returns a different set of IP address records to resolve the FQDN name: err mcpd: 01020066:3: The requested Pool Member (****) already exists in partition ****.
These log messages are cosmetic and do not indicate any impact to traffic or BIG-IP operations.
This message may be logged when the DNS server returns a different set of IP address records to resolve the FQDN name, and new ephemeral pool members are created corresponding to the new IP addresses. This may occur intermittently depending on timing conditions.
'The requested Pool Member ... already exists' messages are no longer logged occasionally when an FQDN pool member name resolves to different IP addresses.
