Applies to:

Oracle WebLogic Server - Version 8.1 and later
Information in this document applies to any platform.

Symptoms

WebLogic Server hangs while writing JTA logs. The client software cannot connect to WLS. There is no error in the application log. We collected a thread dump (kill -3) of the server java process and found the following key messages:

"ExecuteThread: '5' for queue: 'weblogic.kernel.Default'":
waiting to lock monitor 01c96328 (object 2e4cdbf0, a weblogic.transaction.internal.TransactionLoggerImpl$IOBuffer),
which is held by "ExecuteThread: '17' for queue: 'weblogic.kernel.Default'"
"ExecuteThread: '17' for queue: 'weblogic.kernel.Default'":
waiting to lock monitor 01c96528 (object 2e4cdc08, a weblogic.transaction.internal.TransactionLoggerImpl$IOBuffer),
which is held by "ExecuteThread: '5' for queue: 'weblogic.kernel.Default'"

JTA has transaction exceptions and is busy writing them to the JTA log and the server stops responding.
