Good point, its an IBM machine with 16 P4's and 12gig of ram. So its looking like we'll not be able to run it as 1 tomcat process. So it might have to be a cluster of them on the same box. I'm awaiting a bug fix in clustering with big sessions before I can cluster though. Might have to come up with something else to keep us going in the mean time.

What kind of hardware? A single process on a regular x86 machine can only access 4GB of virtual space, regardless of the amount of real memory you have, unless you use some of the OS-specific address extension mechanisms (which the JVM doesn't). If you have an AMD64 and the appropriate version of Linux, you could try the Sun 64-bit JVM (see the 5.0 Beta 3 download list). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
