In one of our 2 servers in a DAG, we keep getting the warning message:

Event 22004 ShadowRedundancy:
The periodic heartbeat to primary server server.domain.local failed.

However everything seems to work just fine (incl. failover). I haven't found any other logs that indicate problems.
Can some one please point me in the right direction what the issue could be or if it's a known bug?

ShadowRedundancy has to deal with the Transport Queue's, and SafetyNet.

Is the Transport service not running on one of your servers?

Hi Jared,

All services are started on both servers, also it looks like this has started after the upgrade from CU7 to CU8.

Hi,

Please check the receive connector configuration in your environment. If there is any useless receive connector, please clear it and keep the default connectors for normal working.
