[jboss-user] [JBoss Portal] - Re: PermGen Space exception
Hi, what we researched was a blog entry from Frank Kiviet (http://blogs.sun.com/fkieviet/entry/how_to_fix_the_dreaded). The examples he used could we completly reproduce. But the result isn't a bug in JDK...

Which is why hot redeploy is not recommended for production, only for development, I can't find it at the moment but there are plenty of explanations about it and relate to some Sun JDK bug that has neven been fixed. Other JVM handles permgen space differently. Unless you redeploy a new version every day you shouldn't have to restart every night. Also on a cluster there are better approach to keep having your portal running without any downtime.

Sorry for my short uncleared explanation. When we do a hot undeploy of an portlet (In case of updating it) and deploy the newer version the classes of the old version wonât release from the perm Gen.

[jboss-user] [JBoss Portal] - Re: PermGen Space exception
What do you mean by "wont be released when they are not needed".? Permgen space is used for loading class definition which is needed throughout the lifetime of serve. Unless a class is being loaded multiple times and there is a leak in class loader, you should not see permgen space grow after certain time. We have not seen any random behavior with permgen space during load testing of JBoss Enterprise Portal Platform (EPP).

[jboss-user] [JBoss Portal] - Re: PermGen Space exception
Thanks for your reply. But the problem isn't the size of the perm gen. The problem is, that the classes within the permGen won't release after they are no longer needed. So the PermGen will grow, grow and grow till you get a permGen Exception. Right now we handle the issue by doing a jojo of the jboss every night...

if your problem is still there: JAVA_OPTS="$JAVA_OPTS -Xmx256m -Xms256m -XX:PermSize=256m -XX:MaxPermSize=256m" Please tune them for your environment :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238169#4238169 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4238169 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

We updated our JDK to 1.6.0_12 but we still get these errors. Is this a known error in Portal or Jboss itself? Thanks in advance.

[jboss-user] [JBoss Portal] - Re: PermGen Space exception
Thanks for your reply, but JRockit is not an option, as JRockit will load the classes in the heap memory. But the classes won't be unloaded too. The heap space grows dynamicly. But the perm Gen from the JDK doesn't grow.

[jboss-user] [JBoss Portal] - Re: PermGen Space exception
Hi Thorsten, I solved this issue for me by using a different Java implementation. Instead of using Sun's JVM, we run the JBoss AS on Bea JRockit. Maybe this is an option for you too.

[jboss-user] [JBoss Portal] - Re: PermGen Space
The problem appears due to hibernate consuming a lot of perm gen! It should be in a wiki, release note, documentation - or even set by default - but it is not :-( To fix MaxPermSize : in jboss server, customize the "run.bat" file set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx1274m -XX:MaxPermSize=256m -Dcom.sun.management.jmxremote To fix it within eclipse, use 3.3.1 or above, and customize the eclipse.ini file to include something like that -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vmargs -Xms40m -Xmx512m View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137915#4137915 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4137915 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

In the AS /bin directory look for the run.conf file. You need to make it: if [ "x$JAVA_OPTS" = "x" ]; then |JAVA_OPTS="-Xms128m -Xmx512m -XX:PermSize=128m -Dsun.rmi.dgc.client.gcInterval=360 -Dsun.rmi.dgc.server.gcInterval=360" | fi View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136588#4136588 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4136588 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

You could also use the JAVA_OPTS in the bin/run.conf, which is maybe easier to find.
