[ http://issues.apache.org/jira/browse/DERBY-1326?page=comments#action_12434296 ] Knut Anders Hatlen commented on DERBY-1326: -------------------------------------------
It is not clear to me why an engine shutdown should close down all DRDAConnThreads. I kind of understand why the sessions are closed (although that would happen implicitly anyway) since their embedded connections are closed as part of the engine shutdown. The DRDAConnThreads are however merely worker threads which don't have any dependencies on the engine instance that was active when they were created, so there is no reason why they can't be reused after the restart of the engine. Does anyone see problems with reusing the threads? In my opinion, it would be easier to ensure a consistent state after a restart if the threads were kept. > Network server may abandon sessions when Derby system is shutdown and this > causes intermittent hangs in the client > ------------------------------------------------------------------------------------------------------------------ > > Key: DERBY-1326 > URL: http://issues.apache.org/jira/browse/DERBY-1326 > Project: Derby > Issue Type: Bug > Components: Network Server > Reporter: Deepa Remesh > Assigned To: Knut Anders Hatlen > Attachments: repro1326.java, resolve_DRDConnThread_conflict.diff, > Restart.java, sessionMgmt1.diff, > sessionMgmt1_and_nosessionsforclosedthreads.diff, > unify_NSImpl_instances.diff, withNewThreadAndNoShutdownOfCurrentSession.diff > > > This issue was found when working on DERBY-1219.
