An error occurred while trying to receive a message over the cluster broadcast.

Make sure that the NIC is functioning properly. If you believe there no environment problems exist, contact Oracle Customer Support and provide the stack trace for further analysis.

More detail and Background information:

Note: Sometimes you get Error Message: and it can be a logical effect of error BEA-003108.

The issue “ Solution

To resolve this issue, the cluster debug flags need to be enabled consistently: either disabled on all the servers of the cluster or enabled on all of them. In a production environment, debugging should be disabled. Cluster debug flags should be enabled only while debugging a problem with the Unicast cluster.

Solution via AdminServer:

  1. Click on Domain Structure and select your Server
  2. Select debugging tab
  3. Select items, that you want to disable or/enable, e.g. Disable weblogic debugging by click on „disable“(german: „deaktivieren“)
  4. Check Log files, wether the issue is solved.
