Installed nvOC 19-1.4 on my new rig, updated it with nvOC-19-2-update, edited 1bash and ZM miner began restarting almost every minute, while Wdog and Temp were showing that all was OK.
Noticed then that not all files and folders in /home/m1 were owned by m1. Did "sudo chown -R m1 /home/m1" and no ZM restart since. May be it's worth adding this command to the
nvOC-19-2-update, just in case.
