Ernie,

The blank page issue has not occured again, perhaps it was a once off glitch.

However you are correct in that we cannot export sequences. And yes Jabber is not running, I will be looking at that later.

Regarding the exporting, any ideas?

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

JAVA_OPTS="-server -Xms128m -Xmx128m"

What should we set it to? Our server has 16gb of ram so we have plenty of spare.

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.

Thanks,

Ernie
