[Wildtangent]

The solution is don't join it xD

[Orameus]

I have had similar problems multiple times with Tekkit. I had three different solutions.

1) uninstall and reinstall the launcher

2) reset host's internet and restart the server

3) make sure you are playing on the right version of Hexxit. Try switching versions and then switch back if that doesn't work.

If all else fails say a Hail Mary

Let me know if any of those fixes it.

[Nonsanity]

This seems to be happening with different modpacks as well, including FTB. This means it's probably a common mod causing the crash.

The general solution I've seen mentioned, and which has worked for me, is to log into single player once, leave that, then log into the server.

[KenGMac]

This seems to be caused by Railcraft Tanks and the chunk they are built in.

Try (1) Changing the Coordinates in your player .DAT (2) Deleting your player's .DAT File.

Good Luck
