Server will not fully start

I’m using MineOS on Virtualbox, commit d529e70.

I haven’t used the server for about 3 months, and have just decided load it back up again. It was a 1.12 vanilla server. The server begins to start (I can see the ram usage slowly increase), then after about 20 seconds I get the “Server down” message. The “latest.log” file for the server is empty.

I tried creating a new server but that also has the same problem. I have attached the mineos log for the test server below, but I can’t see anything useful there. (I replaced my ip address with x’s).

My MineOS installation is stock standard except for Overviewer which I installed months ago (and was working fine).

Any ideas where to go from here?

Can you verify that you have Java 8 installed?

Vanilla 1.12 requires it now, but your installation might still be running Java 7?

Yes, Java 8 is installed:

root@mineos ~# java -version
openjdk version “1.8.0_102”
OpenJDK Runtime Environment (build 1.8.0_102-8u102-b14.1-1~bpo8+1-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

I was successfully running Vanilla 1.12 a few months ago when it first came out.

I worked it out. All it was, was that my virtual machine had run out of virtual disk space (mainly due to weekly archiving). I deleted a few old archives and everything started working properly again.

Does the MineOS GUI give any “low disk space” warnings anywhere? I thought older versions of MineOS (several years ago) showed disk space?
