why does OPC string write cause memory leak?

[yurong]

I use Labview 5.1.1 OPC function to write a string to a string tag in a OPC server. I found that it caused CPU memory to increase every 4k. Does anybody know why and how to fix it?

I believe that there was a memory leak problem with DataSocket 3.0 which came with LabVIEW 5.1. Try upgrading DataSocket to 4.0.

If that does not work, the problem may not have been resolved until LabVIEW 6. Also, if you happened to be using the French version of LabVIEW, contact tech support, there was a specific problem there which does have a work around.
