Server Crashing - Chestshop?

http://pastebin.com/vg7bZvx1

Crash report ^^ Anyone who can help?

 

Your server ran out of memory.

Change the amount of RAM your server is allowed to run.

Code:

#!/bin/sh
BINDIR=$(dirname "$(readlink -fn "$0")")
cd "$BINDIR"
java -Xmx1024M -jar craftbukkit.jar -o true

Assign more ram by increasing the number inbetween -Xmx____M
1024M = 1GB RAM.

 

This only happens when people hold their mouse on ChestShop signs, so if I increase my Ram this wont happen? Currently have 3.5GB with the following plugins: WorldEdit, SimpleAutoMessage, Vault, ClearLag, Modifyworld,Plotme, Pex, Multiverse Core/Portal&Inveotory, CmdSigns, Votifier, WorldGuard, Essentials, Silkspawners and Chatex with around 10-15 players on.

 

ChestShop has a setting for how often to activate a sign when holding down or spamming clicks. Changing that can help your server by slowing down the transactions.

 

Yeah I know, I set it to 5000 (5 sec) still, when they just hold the mouse button the server laggs, and if they do it more than 10 sec or so, the server times out

Anyways, do you guys know of any Shop plugin that is updated to 1.7.9 or close ? I really need a shop plugin, Ive tried GUIShop, but a plugin with more bugs have I never seen.. lol
