[jira] Commented: (GERONIMO-484) Repeated Deploys of WAR Generate OOM Exception
[ http://issues.apache.org/jira/browse/GERONIMO-484?page=comments#action_12329466 ]
Kevan Miller commented on GERONIMO-484:
---------------------------------------
I've verified that the above fixes are working.
I've just run 1500 deploy/undeploy cycles with a max heap of 20 megs. Ran without a problem (I did note that the minimum heap has grown to over 13 megs -- I assume because of the console). However, things aren't perfect. Looks like 1 to 2 megs were lost during the run. I believe most of this has to do with the URLJarFiles mentioned previously. Seems to be an acknowledged Sun bug -- http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4167874 (cast your vote... ;-). It's possible that URLConnection.connection.setDefaultUseCaches(false) could be used to avoid this problem -- it's not clear to me from the discussions on the Sun Bug database and I haven't run tests to confirm (I also don't know how turning off caching would impact current behavior -- it certainly could adversely impact performance).
Shall we close this one out and perform further tests on URLJarFile behavior?

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

> Fix For: 1.0-M5
> Attachments: LogFactoryRelease.txt, minimaltest.war, over-and-over.sh

> 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
> collected will help expose the problem (whether the problem is with me
> 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 appears as if the server is running out of memory. Note that I did
> not alter the native configuration of Geronimo in any way. This is a
> stock M3 download, using JDK 1.4.2_05 on Windows XP SP2.
> It's my expectation that the app server would stay up and running
> indefinitely after redeploys of .war files. Especially this .war file
> since it merely contains a single welcome.jsp. I hope this info is

> My test script:
> $ cat over-and-over.sh
> while /bin/true; do
> java -jar bin/deployer.jar --user system --password manager deploy ../eclipse/wo
> rkspace/MinimalWebapp/build/minimaltest.war
> sleep 1
> wget -q -O - http://localhost:8080/minimaltest/welcome.jsp > /dev/null
> java -jar bin/deployer.jar --user system --password manager undeploy minimaltest
> sleep 1
> done
> Structure of minimaltest.war:
> $ jar tf ../eclipse/workspace/MinimalWebapp/build/minimaltest.war
> META-INF/
> META-INF/MANIFEST.MF
> WEB-INF/
> welcome.jsp
> WEB-INF/web.xml
> Contents of web.xml:
> $ cat ../eclipse/workspace/MinimalWebapp/web/WEB-INF/web.xml
> <?xml version="1.0" encoding="UTF-8"?>
> <web-app xmlns="http://java.sun.com/xml/ns/j2ee"

> <welcome-file-list>
> <welcome-file>welcome.jsp</welcome-file>

> </web-app>
> So, as you can see, it's a very minimal webapp. It doesn't initialize
