[gridengine users] large memory hosts reports crazy memory value when h_vmem is set to 100G or above

Hi there

I'm running SGE 6.2u5 on Ubuntu 12.04 (64 bit). One of my compute nodes
has 512 GB of RAM, but when I specify this (with e.g. h_vmem=500G in the
complex_values setting for the exec host) and then submit a job that
requires a lot of RAM (e.g. -l h_vmem=100G), I get this response:

(-l h_vmem=100G) cannot run at host "bigmemhost.example.com" because it
offers only hc:h_vmem=77309411328.000000

If I set the h_vmem to 99G or below I get a meaningful message, e.g.

(-l h_vmem=100G) cannot run at host "smallmemhost.example.com" because
it offers only hc:h_vmem=92.000G

This definitely seems to be a bug - is there any way around this?

Thanks!
Peter
