I've had this server and world for a while, since 1.8 came out, and this problem has just recently risen.
I started this world (Called 'Askrington') with a friend for building. We've explored the world a bit and have build a few cities. We played on it for a while, the server being hosted on what I'll call 'PC A'. I got a new PC, ('PC B') and I got lazy and didn't move the files over for a while. Eventually, we decided to go on it for a while, but the server would crash as a tick took too long. This 'PC B' wasn't as good as 'PC A', so I moved the server on that PC and it still didn't work.
I moved back to 'PC A', as I got it upgraded and wanted to record/play more games, and I tried running the server again. The same problem arose. I tried re-port forwarding, adding more RAM, upgrading to 1.9, updating Java, changing max tick to -0 (Although the lag was still very noticeable on horses and minecarts), and tried looking for corrupted chunks in single player.
Eventually I decided to try a fresh new world, and it worked. I got the message one time, but got no noticeable lag on the server nor did it crash.
Can anyone help? I really want to use this world with my friend, but we're unable to because of this bug. Here's the crash report for you guys to help.
