reduce memory allocation

[Judge]

Hi,

I use a deployed Teststand 3.1 Sequence on a Win2000 system with Labview Run-Time Engine 7.1 to measure the system behavior during a one week qualification test. Each minute I take measurements of various voltages and digital signals using a NI6229 PCI card. These measurements are saved with on-the-fly report generation and  the activated "conserve memory" option.

Looking at the Windows task manager during runtime, you see a permanent increase of the allocated memory. After 13h there are about 750MB of 1GB RAM used and the sequence is interrupted by an error "can't access Labview run-time DLL ...".

Does anyone knows why there is so much memory allocated and how to reduce it?

In my opinion, there is a connection between the Labview run-time DLL error and the extensive use of the system memory.

Best regards,

Thomas

Thomas,

i state the help for conserve memory:
Conserve Memory and Only Display Latest Results—pecifies whether TestStand periodically purges results maintained in memory while generating on-the-fly reports. If enabled, the displayed report only contains results that have not been previously purged. The purged results are appended to the report file that is saved to disk. Typically, you use this option if executions run for a long period and you want to limit the size of the report in memory. The option is only enabled if On-The-Fly Reporting is enabled and the Report Format is not XML Document. When you enable this option, you must also enable Discard Results or Disable Results When Not Required by Model on the Model Options dialog box.

please make sure that you have set the underlined option.
