[gridengine users] Maximum memory for running process?

[William Deegan]

Rayson,

I initially installed this grid from the binaries here:
http://bioteam.net/dag/gridengine-courtesy-binaries/

The ge-8.0.0alpha*

How can I tell definitively if I have this problem on my install?
I am seeing some maxvmem values over 4GB. But none over 8GB, which is 
not expected.
I would expect to see some at 15GB and higher.

Does this stat get the max for the process tree launched by gridengine?

Thanks,
Bill
