You're right the mem mgmt gets sloppy, but we tried and it made no difference:
SYS(3050, 1, MIN(536870912, VAL(SYS(3050, 1, 0))))
SYS(3050, 2, MIN(536870912, VAL(SYS(3050, 1, 0))))

and even cutting it down by 2 and then by 4 and no difference. It's only happening on one of the VMs. So comparing the VM settings on that is next.

Thanks
