craftbukkit-1.0.1-R1: Tons of errors

1) I hav Windows 7 SP1. 64-bit
2)I have java version 1.7.0

I'm using bukkit for quite awhile now, the problem started when using the "craftbukkit-1.0.1-R1.jar"
Everything starts up normal and it says; Done (0,170s)! For help, type "help" or "?"

A few seconds after that errors start to appear,
I don't know what's happening, I hope someone else can!

If I start the server with 1 or 4 GB of ram, it keeps crashing.

Get Linux.

 

Seems like there are some explosions happening on your server.

If players set off a lot of TNT at once, servers tend to run out of memory like that. Your problem may therefore be unrelated to 1.0.1, as it is most likely just a player that tries to crash your server with tons of TNT.

 

Ok thank you! I forgot that I had been playing with tnt before I updated
