You ran out of permgen space. Try increasing that (-XX:MaxPermSize), it is one of the JAVA_OPTS settings in run.conf or run.conf.bat.

By the way which OS and what version of JBoss AS?

[Gihan Pandigamage]

I already increased the size but problem exists samae.it's windows server 2003 and jboss 5.1

[Peter Johnson]

Are you running JBoss AS as a service using service.bat? If so, have you seen this: https://issues.jboss.org/browse/JBNATIVE-59

If you are not running as a service, when JBoss AS starts it prints out the JAVA_OPTS settings, post that.

[Gihan Pandigamage]

Thank guys it was fixed.
This is the way I fix it.
cut the "set JAVA_OPTS=-Xrs" option from jboss-5.1.0.GA\bin\service.bat file and paste it to jboss-5.1.0.GA\bin\run.config.bat before the "set JAVA_OPTS=-Xms128M -Xmx512M -XX:MaxPermSize=1024M" line
now the run.config.bat file looks like this.

rem # JVM memory allocation pool parameters - modify as appropriate.
set JAVA_OPTS=-Xrs
set "JAVA_OPTS=-Xms128M -Xmx512M -XX:MaxPermSize=1024M"

Thank you very much Peter for helping me.

[Peter Johnson]

And thank you for providing the details on your fix, that will help others later that come across this post.
