What were you doing last time you managed to be on the server? (if you have never joined, say so)
After joining, 5-20 seconds after playing (walking around), the game crashes. I play since the first November without problems until today. It says, "Tesselating block model". It happened while I flied in the end, with my Ruby of Flight by Silent Gems.
I didn't interact with any blocks.

In my crash-report: I added the Mods OptiFine and Xray (Xray is allowed).
