I'm seeing the same problem too. Here's 'top' output on the compute node
Mem: 16440132k total, 16162000k used, 278132k free, 1760k buffers
Swap: 15631204k total, 560672k used, 15070532k free, 2020072k cached

PID 7523 is using 12g, while the qstat for the job shows:
cpu=02:56:06, mem=22080.33477 GBs, io=0.19387, vmem=1.222G, maxvmem=4.030G
I started seeing this problem from 6.2u4 (or u3 I think...). It was ok
with earlier versions.
