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 22:35:23 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1326?page=comments#action_12434299 ] 
            
Bryan Pendleton commented on DERBY-1326:
----------------------------------------

> Does anyone see problems with reusing the threads?

Deepa and I discussed this a fair amount in DERBY-1219; you should
probably review that discussion to see if there's more you can learn from it.
In particular, the discussion regarding "skipThreads.diff" at:
http://issues.apache.org/jira/browse/DERBY-1219#action_12378300

If we didn't close down the threads, would we do anything to notify them of
the shutdown? Were you proposing to leave them alone entirely? Or were
you proposing to notify them of the shutdown, but not require the threads to exit?

Are you sure a DRDAConnThread doesn't have dependencies on the engine
instance? The thread has a pointer to a session, and a session seems like
it could point to database objects (like Connection objects, e.g.)
