Coalwater, Within task manager (or Sysinternals Procexp) right click on the process and select 'Set Affinity'. Then from the pop-up dialog you can select which processors the process is allowed to execute from. And, by doing this it would give a very big hint that the multi-processor environment is what is the big problem. And, in re-reading my previous response I noticed I did not explain why multi-processors can/will exacerbate a poor memory handling software design. This design problem most often will show up in applications which are multi-threaded (multiple threads executing simultaneously). But with a single processor 'simultaneous' really is not. The problem actually comes about when 1 thread tries to allocate memory (usually for a buffer, sometimes for the stack) at the same time as another thread is performing the same function (but with slightly different timings). And without a proper signaling (between threads) design the threads get into a race condition and very soon (or it could take some time) memory becomes exhausted because one thread allocates the memory, the other thread uses it but does not release it because it did not allocate it and the one did not release it because it did not use it. In a single processor environment the 1st thread would allocate, use and release and there would be no problem. This explanation is just a general one as to the type of problem that can be seen with applications designed for single processors, but running on multiple processor.
