Vantage.mfg and 100% CPU

We recently reinstalled Vantage 6.00.522 on our terminal server. The
server itself was upgraded to a new Dell PowerEdge 650. Yet suddenly
whenever our data collection mfg is launched (terminal or locally), the
Mfg.exe process occupies 100% CPU resources for about 45-60 seconds.
Vantage.mfg does not do this. Has anyone seen this or have any insight
on how to correct?

Thanks,

Matt
