John Calcote updated LOG4J2-2860:
---------------------------------
Description:
We find ourselves in a situation where all threads are waiting for a lock in
RollingFileManager, and no thread seems to own it:

This leads me to believe that some thread grabbed the lock and died while
holding it.
We will try upgrading to 2.13 to see if it's been fixed, of course.
