As always, thanks!

Are you symlinking /var/games/minecraft out to your home directory? Are there recursive symlinks somewhere in your logs?

Also, it can't tell if the server is running because you're using spaces in the server name. Spaces can't be handled properly by the screen instance, so MineOS is looking for the screen instance "mc-Realm of Mianite Testing" but the instance that is being created is "mc-Realm"

Spaces == no go in server names.

Spaces == no go in server names.

that was the answer to my question, a clean install seems to have resolved the other issue :)

ciak2009 commented 8 years ago

This issue has returned, the spaces fixed that one, but I am still having this WebUI crash regarding too many open files, the only symlink I'm using is for the archives directory

hexparrot commented 8 years ago

Can you identify the directories specifically that have too many files? My best guess is its on the order of several thousand. If I know which directories, I might be able to determine which parts of MineOS is overreaching. What are the contents of your log directory (file counts, file sizes) if possible.

ciak2009 commented 8 years ago

It seems like its related to latest.log, but this is a clean server, not my typical million file setup :) I did update to Node 5.8 and so far I think that may have helped, not sure though

What server software are you using (minecraft)?
