Memory error on LG with Web script?

I'm trying to run a test that is spreading 490 users across 5 generators. The scripts are all web/html, but are accessing an app that is very java heavy. The test ramps up to about 180 users before they begin getting the infamous C interpreter run time error - memory violation and stopping. One of the scripts has no custom code and no correlation. It is a straight navigate and search.

It seems I can only run about 25 users per generator without getting the error. This seems crazy for web/html scripts. Any thoughts?

Thanks!

Have you monitored your load generators to make sure that you are not running out of memory?

Re: Memory error on LG with Web script?

The generators are maxing out CPU at about 25 to 30 vusers. Normally we can run 1500+ web vusers on these boxes.

Nothing crazy about the run time settings. No logging, replay think time, no cacheing, vuser run as thread.

FYI, generators are Dual Core Opteron Blade Servers (HP BL25p 2218, 2.6GHz DC 95W E6, 4GB RAM, (2) 72.6GB HDD)
