Q: Where does the 5000ms timeout come from when I get “process(Lweblogic.cluster.messaging.internal.ClusterMessage;) timed out after: 5000ms..”?

And we said:

The 5000ms is the currently default value for DatabaseLessLeasingBasisMBean.MessageDeliveryTimeout mbean propety.

This is the stack trace generated by a weblogic managed server leader in a cluster defined with consensus migration in wich another cluster node probably died (or was very busy):
