memory issues with PLC OPC Client


I'm currently trying to use the "PLC OPC Client" from the OPC.llb
Library in a while loop that samples every 200ms. I'm noticing that as i
run just this VI, the Memory usage of Labview.exe in Windows Task Manager
goes up quickly where after an hour, Labview.exe takes up some 150MB of
ram. Not good. Is there anyway around this problem i'm having? I'm not
familiar with memory-dumping VI's or strategies....

OPC.llb can be found in the \examples\comm directory of labview 6i.

I couldn't find any VI with this name in the OPC.llb. I would recommend starting a support request with National Instruments. You can go to and select Email NI as the communication method.
