John,

Good suggestion, but "unfortunately" I already run it as an administrator. Bad security practice, but as you say, it can eliminate odd problems.

The Meltdown/Spectre patch has caused a noticeable performance hit on my machine, even though it is very capable. I am wondering if it may be causing a timing problem? Fortunately the problem only occurs every 2-3 days, but is annoying for unattended operation. SatPC32/Labjack have been running flawlessly for literally years.

Erich,

So far the stalls have occurred in the middle of the night. One was showing the elevation at 4 degrees, with the target at 0. The Labjack server was indicating a down command. I closed and restarted SatPC32 and when I selected Park, it dropped to 0 and the desired azimuth. The second time was an azimuth problem, with a large difference between the commanded and actual position. The Labjack server was indicating a turn. Closing and restarting cleared the problem.

There are two changes that I know of. I recently changed the rotor position change window from 3 degrees to 10 degree to reduce wear, as that is close enough for LEOs. I have reset that to 3 degrees to remove the variable.

Mark, G0MGX suggested that I look at KB4103718, which has been reported to be causing some USB issues. I have removed it, and will see what happens. If it happens again, I will get more details. It certainly looks like something in the OS rather than SatPC32.

Quick progress report.

After deleting KB4103718 and resetting the rotor position change to 3 degrees, I have not seen a stall in a week. I will open that out a degree at a time, and see what if anything happens.
