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:
2018-02-10 5:00:18 AM|# connection closed by server r:0
2018-02-10 5:00:18 AM|# reconnecting

2018-02-10 5:00:30 AM|stratum subscribe failed
That was the last thing recorded before the crash.
right before the crash.
I'm not sure why this is happening all of the sudden as it's been really stable for awhile.
