First of all I thank you very much for your time and response. So far I did the same thing as mentioned in the article and elevated the limits, and yet haven't encountered the problem. Furthermore, I would like you or some other experts to please shed some light upon the difference of JVM for 32-bit and 64-bit in this scenario. Thank you once again for the help and regards, --muneeb View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233857#...
