I am having the same problem with my multiplayer server. The game would crash when I logged in, so I deleted my player file, just in case it was some corruption in the chunks I was in, and it worked – until I decided to start putting lots of cute, colorful parrots around the spawn area. After spawning about 15 or 20 parrots, the game crashed again. The area I had been in prior to deleting my player file also had parrots (also spawned from eggs).
I have had the same problem on my hamachi LAN world. When reverting to anything before 17w13a everything is working and everyone can connect.
