Its holding better i haven’t seen it restart in the past few hours i think MMM-watchdog was the problem

@richland007
Unless someone tells different, from my point of view you do not have any CPU or memory issues.
In fact, it makes me wonder why I am seeing the electron.js processes so high in my output.I do not use MMM-watchdog and I do not know exactly what it is doing.
Do not know what it is pinging, but something on your MM makes it time out and as a cause it restarts mm.
The log only tells you that it failed, but not what exactly failed.
Would be nice to know how you can send this ping manually, then you can observe the behavior yourself.I take it, that you have your monitor connected to your Pi.
So MM not running as server only and the display not on a client.Anyway, good to hear that you potentially have found the issue and you learned a bit of Linux on the side.
