Looking at the files on the server, I found this peculiar one: /home/minecraft8/world/region/r.4194303.4194303.mca

Using Dinnerbone's coordinate Tools, I see this corresponds to the region containing blocks 2147483136,0,2147483136 to -2147483649,255,-2147483649.

2147483136 is the max value for an Unsigned Long.

So the crash cause seems to be that in Minecraft, you can have a player's position set to the max Double value, but you can only have a stored block coordinate set to the max Unsigned Long value!

Thus it's impossible to generate the block/chunk/region where the corresponding player is supposed to be!

The position is not "resetted to the end of the known universe" (the Minecraft world border is only set to 60000000 on the x/z axis) but "resetted far far away beyond the known universe" :-)

Of course, this does not explain why this happens at all in the first place, but it's funny to know...

I sense a vergence in the Force here!
