Hi Lachlan, I've just came across something that might be able to shed some light into the issue regarding blank pages. Recently I've had a LAMS server that was experiencing some heavy usage and it ran out of memory. Using JAVA_OPTS you can specifically assign the amount of RAM memory you want a java application to use. In your run.conf file in your jboss-4.0.2/bin directory, you'll find a line that starts with JAVA_OPTS = "...." Can you please paste this line here? I believe you might have experience a similar issue, so if you increase the memory allocation to LAMS, that will prevent this from happening. Thansk, Ernie Posted by Ernie Ghiglione

JAVA_OPTS="-server -Xms128m -Xmx128m" What should we set it to? Our server has 16gb of ram so we have plenty of spare. Posted by Lachlan Hockings

> JAVA_OPTS="-server -Xms128m -Xmx128m" Woow.. that's very very bad! LAMS would run out of memory very quickly. I'm almost certain this was the problem with blank pages now. For production, I would suggest a minimum this: JAVA_OPTS="-server -Xms256m -Xmx2048m -XX:MaxPermSize=256m" After this, you won't have any problems even with 500 concurrent users.
