Opterons, MM5 and pgi 6.2

Hi!
On our university we have a 8 cpu opteron computer with pgi 6.2 compiler and we wanted to test MM5 on this computer but have problems running MM5. After some seconds we get segmentation faults. Are there any known bugs with opterons, MM5 and pgi 6.2?
We used as a testcase only 1 domain with 64.8 km resolution, it can’t be a lack of memory.

MM5 and WRF crashing during execution is very often due to not enough
stack space.

limit stackspace unlimited

is ‘limited’, and often not large enough.

I assume this is 64-bit, so try

limit stacksize 3000M

for example, and see if the programs complete.
