I have an opportunity to resolve. We use the same install process for all of our application servers. We load the op-sys (CentOS 6) using a pxe-boot process and a standardized kickstart file.

So wouldn't you know, I have one server out of 10 on which we may not create a java heap space the same as all the others. WTF??

Our standard test is java -Xmx2560M. On all systems but the one (that the boss HAS to have!) this runs and generates a grocery list of commentary. On the bad boy we get:
        Error occurred during initialization of VM
        Could not reserve enough space for object heap
        Error: Could not create the Java Virtual Machine.
        Error: A fatal exception has occurred.  Program will exit.
The largest number we may use on this machine is java -Xmx1024M.

Now for some contradictory information. Yes, we build our applications on the 32bit version of CentOS 6 (PAE). This particular instance (VM guest) has 12GB of memory allocated to it and the VM host has 32GB, not saturated.

Thoughts (besides slashing wrists)?
