Subject [jira] Commented: (DERBY-594) Some rawStoreDaemon threads are not stopped
Date Wed, 01 Mar 2006 21:10:39 GMT
    [ http://issues.apache.org/jira/browse/DERBY-594?page=comments#action_12368363 ] 

Daniel John Debrunner commented on DERBY-594:
---------------------------------------------

Confirmed that this is not an issue for DERBY-538, the raw store daemon thread stops correctly
in the situation I'm seeing.

>          Key: DERBY-594
>          URL: http://issues.apache.org/jira/browse/DERBY-594
>      Project: Derby
>         Type: Bug
>   Components: Services
>     Versions: 10.1.2.0, 10.2.0.0
>  Environment: Solaris 10 x86, NetBSD 2.1 (x86), Sun JDK 1.4.2/1.5.0
>     Reporter: Knut Anders Hatlen
>     Assignee: Knut Anders Hatlen
>     Priority: Minor

>
> In some cases, loading a database will create a rawStoreDaemon thread
> which will run forever, even after Derby is shut down with
> DriverManager.getConnection("jdbc:derby:;shutdown=true").
> I have found two tests in derbyall (there are probably more) where
> threads are left running:
>   - in store/rollForwardBackup.sql two threads are never terminated
>   - in store/encryptDatabase.sql five threads are never terminated
> All the threads are named "derby.rawStoreDaemon" and created in
> org.apache.derby.impl.store.raw.RawStore.boot().
> It seems like this happens in some (but not all) cases where the
> loading of a database fails, but I am not able to say exactly what
> triggers this bug yet.
