Sorry, that was written under confusion. I meant for the original poster and his monitoring of virtual/resident memory and the fact that he seemed to have a legitimate OS level out of memory condition. In other words, I recommend that to the OP just to remove one variable in terms of monitoring what is consuming memory. -- / Peter Schuller
