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.

Using the browser navigation buttons does not correctly change a query

On pages with a query panel (Assets, Calibrated Assets, Reports, etc.), the browser back button does not work as expected. When a user presses the back button, the URL in the browser changes, but the filters do not.

Workaround:

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

Test results group by selection is ignored when a filter is changed

The Test Monitor test results table allows grouping results by property. When a user selects a group by property and adds a filter, the group by behavior is incorrect. Results are shown separately instead of grouped.

Workaround:

Select a different property to group by and then re-select the original property to reset the table.

SystemLink Client performance degradation over time

The SystemLink TrayApp on the client system starts a tcp-server in order to get job notifications. This mechanism enables pop-up notifications informing the current user that a job started/completed. This has to work for any user that can login to that system and for Windows Server we have to support the use-case of multiple users being logged-in simultaneously; each user has their own tcp-server on its own port.

The ports are persisted on the disk in this location: C:\ProgramData\National Instruments\Systems Management\NIMinionConfig\ports

Over time, this list may grow and will include users that are no longer active on the system. For each port that fails to connect, there is a 2 second timeout when attempting to connect. This results in delays of 2 seconds multiplied by the number of inaccessible ports for each job.

Knowledge Article associated with this issue: 

    Workaround:

    Manually delete the files corresponding to the users that are no longer logged in to that system.

    TDM DataFinder Optimize Database function does not reduce database footprint when run after data is deleted from MariaDB

    In version of DataFinder Server Editions prior to 2014, executing the TDM DataFinder Optimize Database function would reduce the database footprint roughly proportional to the volume of records deleted from the database. This function could be used to help cleanup database after archiving old data. This does not function as expected when run after data is deleted from MariaDB

    Workaround:

    Setup multiple DataFinder instances and archive the entirety of the oldest database at a time, cycling through several instances to achieve desired volume of historical data storage.
