VISA resource error in TestStand

[yangyang-rexxar]

Hi all,

I have a vi to operate Agilent 34405A DMM.

The vi is called by TestStand sequence,it always work fine.

Suddenly it show me an error such as "Insufficient system resources to perform necessary memory allocation,-1078807800"

Then I restart my PC and DMM, It works well again.

I want to know why?Any math to fix it regardless it is indeterminism.

paulbin,

that error indicates some kind of memory leak in your application. Please make sure the all references are closed properly during runtime. You can observe this during runtime by watching the meroyallocation in the task manager (or performance found in control panel >> control).
Possible solutions:
Find the leak and free all resources after each call. You can give a try a change in the loading and unloading options of your LV-step communicating with the DMM.

hope this helps,
