Subject [jira] Commented: (GERONIMO-484) Repeated Deploys of WAR Generate OOM Exception
Date Thu, 11 Aug 2005 21:54:54 GMT
    [ http://issues.apache.org/jira/browse/GERONIMO-484?page=comments#action_12318548 ] 

Kevan Miller commented on GERONIMO-484:
---------------------------------------

Thanks David. 

Things are looking pretty good. Looks like the remaining o.a.g objects being leaked are caused
by the JettyWebAppContexts problem described in (2). Once that's fixed, I'll rerun to see
if any non-o.a.g objects are being leaked...

>      Project: Geronimo
>         Type: Bug
>   Components: web
>     Versions: 1.0-M3
>  Environment: WinXP SP2, JDK 1.4.2_05

> Hello,
> I have just run a test that tests Geronimo's ability to redeploy .war
> files.  The results don't look so good, but I'm hoping the info I've

> or the server :)
> I've included the script, .war file, web.xml, and two exception traces
> (one from the deploy client and one from the server)  I apologize for
> the length of this post.  If there's a better way to include all this
> information, please let me know.

> It's my expectation that the app server would stay up and running
