It May be Posible to have two leases for the same client because they are tracked by jvm id. This results in leases being closed on the server without notification to the client. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBMESSAGING-1262 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1262 Project: JBoss Messaging Issue Type: Bug Affects Versions: 1.4.0.SP3_CP01, 1.4.0.SP3 Reporter: Jay Howell Assigned To: Tim Fox Platform: EAP 4.2.1, JBM 1.4.0.SP3, JBREM 2.2.2.SP5 (pre-release) After a short-network outage, if a JBM client detects the error, and reconnects to the JBM server before the original lease expires, then the JBM server will clean up resources associated with both the original connection, *and* the new connection, once the lease expiry occurs. The JBM server appears to track client sessions by a client JVM id, assuming that a single remoting invoker/lease can exist for a given JBM client JVM at any given time. However, in the error scenario described about, two leases associated with the same client exist on the JBM server for a short period of time, until the first stale lease expires. The net effect of this problem is that healthy sessions are closed on the JBM server, but are never detected by the client, since the new client lease pinger continues to functioning correctly. Testcase: 1. Configure the lease timeout to a high value (e.g. 60 seconds) 2. Pull a network cable causing a JBM subscriber to disconnect. The network outage should be < 2 * lease expiry 3. Restore the network cable, allowing the subscriber to reconnect 4. Wait for the original lease to expire on the JBM server 5. Observe that all subscriptions (including the new healthy ones) to the client have been closed -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
