UPDATE
Posting here, cause the server status post is currently locked. As I understand the current problem, part of the server seems to be crashing (login) and the main server isn't recovering it like it should? If that's the case I'd like to put forward a temporary fix (so to speak). I've hosted a ton of servers in my time and, on occasion, some of them haven't been what I'd call entirely stable. That said, some time ago I came across this freeware developer who had a pretty solid Server Monitor. He goes by the name Jimbob Slimbob. His server monitor is pretty powerful and offers a ton of configuration options to, basically, watch an executable to make sure it hasn't stalled, crashed, or shut down. If it does, it restarts it. I've had it work with Minecraft, 7Days, The Forest, and many other servers. Again, it's completely free with no ads or anything. The dude made it because, like me, he loves gaming and hosting servers. Only catch is it's Windows based, and I'm not sure what your E&B server operates on. Anyway, if you want to check it out, here's a link to his site;
