Opened: Aug 06, 2019
Severity: 3-Major

Symptoms

In rare circumstances mcpd may core when resetting its DSC connection.

Impact

mcpd cores and restarts. This results in a failover to the next active peer.

Conditions

The exact conditions are not known for this to occur. The BIG-IP system must be in a Device Service Cluster, and must have configuration sync enabled. It might be related to when an Administrative BIG-IP user makes manual changes to the device trust group that would cause the trust to be broken (and optionally, re-established).

Workaround

None.

Fix Information

None
