Crashing all the time, not a 20second hurpdurp!

Hello everyone, I have been crashing ALOT as of late and I was wondering if anyone had any ideas as to why. Here is some info:

java.net.SocketException: Connection reset
at java.net.SocketInput.Stream.read(Unknown Source)
at java.net.socketInputStream.read(Unknown Source)
at java.io.FilterInputStream.read(Unknown Source)
at net.minecraft.server.packet.b(SouraceFile:113)
at net.minecraft.server.NeworkManager.f(SourceFile:155)
at net.minecraft.server.NetworkManager.c(sourceFile:9)
at net.minecraft.server.NetowkrReaderThread.run(SourceFile:62)

That is the error that pops up on the console of the server I run when I crash, (or a friend of mine who has this happen much more rarely.)

I have uninstalled and reinstalled (Clean installs); Java(Version 6 Update 24), and Internet Explorer(some programs like to use this, and it's number 9now).

I all so have defraged,cleaned my registry, deleted temp files, and ran my virus/malware scans. (not in this order.)

My driver for my network adapter is up to date.

Now than, the server. It's a bukkit (0.0.0-544-g6c6c301-b556jnks) server and the plugins are as follows.

Appletree-leaves can drop apples/gold apples
Worldedit- Wand=editing the world!
McMMO- Skillups/what not.
Sponge- Sponges work again!
Pumpkin Diver- Pumpkin on your head before diving allows you to dive/build underwater 10x longer.
SafeKaboom- Tnt/creeper's don't destroy blocks, just do damage/knock back.
BigCatch- Fishing addon, random stuff happen when fishing.
Heroic Death- When you die a funny message pops up so we get to laugh.

The server is privet(a few friends.) so no bigbrother/griefer stuff.

My comp is Windowsvista(I know) SP2 64bit.
Intel core 2quad q9300 Quad core
Nvidia Geforce GTX 260
6+gbs ram.
640 GB hardrive.
and highspeed internet. (10+megs.)

Not sure what else to post.

The crashes happen randomly, form killing mobs, to trees, to building, to standing around typing.

My ports are foreworded.
Any ideas?

I'm not running any wrappers

If I missed any more info, please let me know. I covered everything I could think of.

Bumping for great justice. I would really like a bit of help with this. If I posted this on the minecraft forums all they would do is troll me into posting it here.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I'm having the exact same problem, same error message.
Running CB 556.

Can anyone help us?

 

Just got up so bumping again, this time not just bumping for my self, but all so for Cubox. Help the cubox, love the cubox. Aid us in this time of need.

Only you can save our sanity.

 

The "exception" in the console is just shown when a client quits.
Your problem is a client issue if it's the client crashing (Which from the sounds of it it is) as that exception should only be thrown when the client disconnects from the server (There's about 3 different "exceptions" the server throws on disconnect)

 

Just reintalled both minecraft and the server.jar

Still crashed within a few moments of connecting to the server. The only thing I can think of is a complete reinstall of bukkit. If I do that I would lose a lot of data and was hoping to avoid that.
