Could you please send us a system report so we can have a better overview about your system?
Yes the system report was taken before the update. Subsequently I did update the CORE to RM21.11 Patch 6 (system apps and application apps) but the machine continues to shutdown with license errors. This happens roughly every 1.5 - 3 hours. The system time is always correct. It seems there is a license check that happens in the backround every so often that fails for unknown reasons.
Also we notice that the start date for all the licenses is 01-12-31. This seems odd, but it is the case in other CORES also. Please see screenshots below and attached video. Here is the CORE archive ctrlX_ctrlx-CORE_2022-04-25_11-38-49.tar. Maybe there is a hint within or you can replicate the issue. (archive was before version update, but as mentioned the update did not help).
We found that in your case you created in a python script a loop without any waiting time in your main program. The same in your test program. It is like an C++ or PLC while loop without an exit it will grab all system resources it can get until the system collapses. You mention this with data layer not reachable, licenses cannot be checked and system is rebooting. So please add a waiting time your programs like this:
