This is most visible using the tcp connector because it detects dropped connections faster than the rmi connector. The problem is due to a race condition between the server cleaning up the disconnected connections, and a new durable subscriber being registered with the same name. If the connection cleanup occurs after the new subscription is registered, it removes the new durable subscriber as well. To reproduce: 1. configure openjms to use the tcp connector 2. download and compile the attached Reconnect test client 3. run openjms on one host 4. run the test client on another host 5. Run a publisher on the server host, publishing under topic1, using PERSISTENT delivery. Publish 10000 messages or so. 6. Disconnect the network connection between the two hosts. 7. When the client throws an exception, reconnect the network. The client should reconnect to the server. 95% of the time, the client won't receive any messages as it has been deregistered by the connection cleanup. ---------------------------------------------------------------------- >Comment By: Tim Anderson (tanderson) Date: 2003-06-24 21:59 Message: Logged In: YES user_id=557161 Fixed in CVS.
