Memory-usage of teststand when nothing runs

[OnlyOne]

Hello,

i have a testplan and checked the memory for teststand and labview after each run.

After load:      LabView            50MB

                     TestStand         110MB

After 1. Run:     LabView            70MB

                       TestStand         120MB

After 2. Run:     LabView            70MB

                       TestStand         126MB

After 3. Run:     LabView            70MB

                       TestStand         125MB

After 15min break:     LabView             70MB

                               TestStand         140MB

As we can see Labview ist always constant after the first run and all VIs are loaded into memory.

The interesting part are the last numbers. There i made a 15min delay (just did nothing with the computer after the third run) but the memory was 15MB higher. Any ideas why?

Why grabs Teststand memory when there is nothing running?

Thanks

Hi OnlyOne,

what versions of TestStand and LabVIEW are you using?

Can you also see the memory leak when you run a standard example, e.g. computer mother board test demo?

Its Labview 8.5 and TS4.1.

The testsystem is at a customer-place so i cant test it.

Hi,

maybe this KB helps with the memory leak, but I don't think that the phenomena described there would create such large memory leaks.

Other than that I couldn't find any out of the box answer to your question. We can only try to exclude several influences and find the root of this problem this way. Maybe you can guide your customer through one of the examples.
