So a weblogic FileStreamHandler and a ConsoleHandler are deadlocked ? What is the logging implementation ? Is it commons logging or log4j ? If log4j then do you have a console appender and a file appender ?

Could be related to this -> https://issues.apache.org/bugzilla/show_bug.cgi?id=41214

Is that the full content ? Where is the console appender ? Try removing the Console appender. Are you able to reproduce the problem after that ?

From the logs, it looks like you do -> ExecuteThread: '60 is waiting for a lock on ConsoleHandler.

Also looks like java util logging calls the WL logging implementation
