ESS Absence request Error : Lock Exception

Hi,

When a user is trying the absence request application , she is getting the following error, she is the only user getting the error.

We did a server restart but that didn't solve the problem.Please suggest

#2#sap.com/pb/PageBuilder#com.sap.tc.webdynpro.services.session.LockException: Thread SAPEngine_Application_Thread[impl:3]_36 failed to acquire exclusive lock on client session ClientSession(id=(J2EE258694500)ID0000822451DB11319429603123595159End_1457644797). Existing locks: LockingManager(ThreadName:SAPEngine_Application_Thread[impl:3]_36, exclusive client session lock: ClientSessionLock(SAPEngine_Application_Thread[impl:3]_35), shared client session locks: ClientSessionSharedLockManager([]), app session locks: ApplicationSessionLockManager([]), current request: sap.com/pb/PageBuilder).Hint: Take a thread dump of the server node to find the blocking thread that causes the problem.

    Hi,

    Have you deleted the locks from system administration->Monitoring and under portal check object locking. see if there are any locks and see if you could delete the locks.

    If the system is hanged you can restart the server0 (or server<n>) node to resolve the issue, but the issue may recur. Permanent solution is described in the note 1234847. There is a ppt attached to the note, you can proceed as described there.

    Cheers!!!

    Umang 😊
