Ok, so it happened again today that there was a disconnect and my AMD rig mining on Claymore recovered, but both my nvidia machines hard crashed DSTM so mining stopped. This is really weird as I had been running DSTM for a couple of months and this behavior only started in the last week or so.
I was previously mining on suprnova, so I switched to nicehash to see if the pool was the issue but no, it still happened.
All I see in the log is below:

That was the last thing recorded before the crash.
