If you remove or attach a different monitor to an fqdn pool, then perform a full config-sync, an error occurs: Load failed from /Common/bigip1 01070712:3: Caught configuration exception (0), Invalid monitor rule instance identifier: 58. This error can occur on FQDN nodes or regular nodes. It's the use of fqdn nodes that allows this issue to occur.
You might experience the following: -- Sync to the peer devices fails. -- Monitors may be stuck in an unexpected state such as down (even with a good reply) or checking even though an up or down response is received.
-- BIG-IP device is configured with fqdn nodes/pools with monitors. -- Modify an fqdn pool to remove or attach a different monitor. -- Run the command: run cm config-sync to-group Failover -- Perform a full config-sync.
Use incremental-sync. If incremental sync fails to correct the issue it can sometimes be recovered by running the following command: bigstart restart mcpd Note: Traffic disrupted while the system restarts.
