Anonymous,

That will only postpone the problem. Because the memory is never released, eventually you will still hit the problem.

The solution proposed by Raghav in the comments is the easiest solution.

This is mainly due to small size of permanent generation of heap.just increase size by using JVM option -XX:MaxPermSize=256m” as shown here

[…] found some great articles, but the comments left behind by this particular user nailed it (Raghav http://blog.yannis-lionis.gr/?p=8). There were even some silly suggestions like switching to JRockit. Well ignore […]

Thanks, this information is really worked.

set JAVA_OPTS=-Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=512m -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Thanks a ton

NikhilR,

The error to me means that your machine didn’t have enough free memory available in order for JBoss to initialise with the given JVM memory options. That seems a bit unlikely on a 4GB RAM machine, but then again it depends on what other things were running at the time and how much memory was free. I suggest trying to lower the memory needed by JBoss progressively until you get something that works and closing most other applications on the machine to maximise available free memory.

Thanks Yannis, Raghav,

I had the same error, and tried the JAVA_OPTS params you has suggested. Unfortunately I then get this error on starting JBoss

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Press any key to continue . . .

I am on a Win XP 32 machine, with 4 GB of RAM. Any suggestions ?

Thanks

Perhaps a better way to put it would be that, if a foreign cuisine restaurant attracts foreigners from that country, especially non-tourists, then they must consider it an accurate representation of good food back home, authentic in other words. Most of the time, that means it’s a place worth visiting. Sometimes, it’s just McDonalds.

“it’s always a good sign when people from the country the cuisine originates from frequent the restaurant.”

Alexi Sayle has pointed out the flaw in this argument, as there are plenty of English people in Little Chef.
