Asset self-calibration status does not update after unlocking a locked system

Attempting to start an asset self-calibration on a locked system will correctly show "System Locked (changes suspended)" under Status. If the system is subsequently unlocked, the status will change to "Self-Calibrating" but will not update further. This issue is cosmetic only, and the self-calibration completes correctly.

Workaround:

Run the self-calibration again with the system unlocked to reset the status.

Remove the filter using the X button next to the property selection field instead.

Background monitoring can cause tests to periodically fail

SystemLink periodically reads the calibration and temperature information for all NI assets every 5 minutes.  If SystemLink is reading the temperature at the exact same time an automated test is run it can cause the test to fail if the driver reserves the device while in use.

Workaround:

Lock your systems before running tests from SystemLink.  This will prevent the background tasks from running.

Stored test results can be sent to the incorrect server when client registration is changed while forwarding is in progress

If the store & forward plugin is already loaded and forwarding steps, it continues to forward to the original server connection even if the server is changed.  It will not switch servers while there are current transactions on disk and still successfully forwarding them.  Since simply switching the master does not invalidate the old API key, then if the server is still accessible, the forwarding plugin does not know that it should switch to the new master.

Workaround:

There is currently no known workaround for this issue.
