Applies to:

Oracle WebLogic Server - Version 10.3.6 and later
Information in this document applies to any platform.


4 managed servers in a cluster, 2 on each machine (Super cluster Zones). After abruptly shutting down one of the zones, the managed servers on the other zone cannot be started. It hangs at the following stage:

Starting service weblogic.server.channels.EnableAdminListenersService, 79 of 132.

Last service weblogic.server.ServerLifeCycleService took 0ms.>

After this, several thread dumps were collected. Thread dumps shows, two threads that are involved:

After about 18 minutes, saw the following:

<Channel "DefaultAdministration" is now listening on for protocols admin, CLUSTER-BROADCAST-SECURE, ldaps, https.>

However, after this message, the server still struggled to connect to AdminServer and we see following exceptions in server logs:
