Symptoms

The WebLogic and Enterprise Manager Console hangs after providing credentials. Following are the main symptoms:

• Start AdminServer using "startWebLogic.sh"
• An attempt to login to WebLogic or EM console will hang. Example using below links:

http://<hostname>:<port>/console
http://<hostname>:<port>/em

• During this time if we try to stop WebLogic via stopWebLogic.sh, it also hangs as it cannot connect to stop the process. Will need to do "kill -9" etc to stop.
• After starting AdminServer with startWebLogic.sh, and then if  we start Reports server "startManagedWeblogic.sh WLS_REPORTS http://<hostname>:<port>", prior to accessing console then WLS_REPORTS starts successfully and can do showjobs or showenv.
• If wrong credentials are given for console login it returns immediately with error.

From analyzing the thread dumps collected from the AdminServer, when the issue happens we saw the following stack trace related to WebLogic and EM console login being blocked.

 Solutions in <Note:2639731.1> did not work here.

Changes

 This issue started happening after a VM reboot on the client side.
