We found this while troubleshooting a message driven bean getting stuck. Notice that the `activeSessions` list contains the same ServerSessionImpl object twice: <img width="1647" height="786" alt="Image" src="https://github.com/user-attachments/assets/305830f8-4abe-4178-a348-c802e135ddf7"; /> The culprit is most likely that the manipulation of the running flag and the `returnToPool()` invocation are prone to a race condition: https://github.com/apache/activemq/blob/69ecc88f8c01547ddebf2346193036252059f074/activemq-ra/src/main/java/org/apache/activemq/ra/ServerSessionImpl.java#L201-L202 The pool might reuse the session before `returnToPool()` is invoked: https://github.com/apache/activemq/blob/69ecc88f8c01547ddebf2346193036252059f074/activemq-ra/src/main/java/org/apache/activemq/ra/ServerSessionPoolImpl.java#L181-L189 The duplicate idle entries are than eventually carried over as duplicate active entries. -- This is an automated message from the Apache Git Service.
