matlab routine within labview cannot get input after a few hours of use. What can be the trouble?

I have a Matlab-within-Labview application that needs to run 30-40 times in a row. However after let's say 10 runs I get error 1047, that is, there is no communication between Matlab and Labview. I have to reset the computer to start re-running the application without problem. Note that Matlab is open on this computer all the time.

Hello,

The only information I could find on this from NI or MWorks is that MATLab must be running in order for LabVIEW to access the Matlab server. I would check to see if there is anything specific happening inbetween the 10 and 11th runs that causes the link between the Matlab server and LabVIEW to break, isolate where this happens and try to work from there.
