Teststand slows down during overnight testing

[Chris46]

Hello All,

I have Teststand 4.2 and labview 9.0. I need to run a number of tests repeatedly where the duration of testing could be typically 48 hours. I have just started to run these extended tests but have found Teststand slows down after a number of hours to the point where I noticed a 1 second wait step takes 4-5 seconds to run. At this point the test system results are invalid.

I have looked on the NI userforum and believe the issue relates to the report results getting larger and larger to the point where it reduces the performance of the PC. I have used the Teststand settings described here:

Is this the most efficient setup? I imagine theres a way to tell Teststand to save all the results every minute then flush the buffer so it doesnt affect the testing. I noticed the "Configure > Report Options > conserve memory ..." option stops results being logged when I terminate the sequence.

Thanks In Advance

Regards

Chris

Hi,

If you are storing loads of results due to long execution runs then you need to use 'On the Fly' result logging because of the problems with the result being in ResultsList which will just grow and grow until you run out of memory or TestStand crashes.

Hello Ray,

Thanks for the response. I ran a sequence overnight and found the machine still running as expected this morning however when I stopped the sequence I dont have any results. So the problem is half resolved. I followed the settings in the above link but must have missed somthing.

Advice Appreciated

Regards Chris
