A few days ago I setup a low-spec 3 node cluster (3 servers) running Cockroach 1.0.2 on a Vultr VPS. I left an ssh connection open and connected to the command line client. When I switched to the ssh terminal window I found the following errors:

I’ve been using Vultr for database, web, and other hosting for a couple of years and have never run into this sort of message.
