Subject [jira] Commented: (DERBY-1326) Network server may abandon sessions when Derby system is shutdown and this causes intermittent hangs in the client
Date Tue, 12 Sep 2006 22:20:23 GMT
    [ 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.
