@michael_f @Wayne-Workman @Hanz a patch has been developed and verified for this issue. It will be released with 0.11.6 (along with a few other new features) once release candidate testing finishes for the client.
If that’s the case, this can be marked as solved. Thank you everyone! It appears that most of the random shutdowns in my district were caused by some sort of dirty power situation. We’ve discovered Daisy-Chained powerstrips on problem PC’s (GRRRRR) and in one case we think the actual wiring in the room (the building and wiring is really old) may be causing random shutdowns. We are installing a mini UPS there tomorrow. Just out of curiosity does anyone else have random shutdowns on Dell Optiplex 5040’s? It may be that they are very sensitive to dirty power, or maybe a design flaw… We pulled our hair out over this for weeks on this.
