Just wanted to post here with 1.1.3 my server has been amazingly unstable ( 3 crashes so hard I had to reboot the server manually ) and its been everything from Java itself crashing to forge crashing, and just my server locking up and not responding to input ( Read above ) I don't know whats causing this but I've been going threw the logs and the only consistent thing is the Gravestone mod, and YABM... the 3 hard crashes look like it was trying to start a backup and failed so the server just hanged.
EDIT: Disabled YABM and my server is running 10 times faster, will update this post with more news lol.
EDIT2: Running the Admin Command Toolbox pregenspawn 1000 command and it has gone farther then any other attempt so far so i think its safe to say removing YABM fixed my problem. Just posting this here for other people that may have similar problems with it.
