Hi

Can you define what you mean by 'machine crashing'.  Do you really mean the hardware crashes i.e. powers off or reboots?  Or that the application crashes.  An actual hardware crash would be odd and would look at whether the CPU or RAM are over-clocked.  This could cause either to run hot and the heat dissapation capacity of the compute node to be overwhelmed.  

If you really mean the application can you post any warnings and errors found in the Solution Output.
