Motion Slowing After 10K moves

I have  a PXI7344 motion control drive.  I am passing in a aray of XYZ data (150K lines).  After performing about 10K moves, the system slows down exponentially, slowing from about 3.5 Hz to eventually (over a couple of hours) to .5 Hz.  Am am using typical Labview commands, loading the vector space and then starting, waiting until the move is complete, and then executing the next line.  The system appears to be hanging up at the move complete step, but I'm not sure.

Paul,
 
Could you post your VI, or a screenshot of your block diagram so that I can take a look at it?  Thanks.
