Bukkit

What steps will reproduce the problem?
1.Resyncing account in-game with /resync

What is the expected output? What do you see instead?
Instead of re-syncing the accounts, the server becomes inresponsive, the CPU usage and the RAM usage skyrockets.

What version of the product are you using?
I'm using v3.4.0 with CraftBukkit version 1.1 R1

Do you have an error log of what happened?
There were no errors, so i presume it's an error with the config.
But here is the startup:
OKB3: Attempting to enable OKB3 v3.4.0 by Kalman Olah...
OKB3: Initiating auto-update...
OKB3: You already have the latest version of OKB3.
OKB3: Configuration file loaded.
OKB3: [DB] Initializing MySQL connection...
OKB3: [DB] Loading database...
OKB3: OKB3 v3.4.0 enabled successfully.
OKB3: Hooked into iConomy version: 6...
.............................................................................
And when i joined:
CONSOLE: Airsoft742 has logged in.
OKB3: [SYNC] Airsoft742's ranks successfully updated.
CONSOLE: Airsoft742 joined the game.
OKB3: [NICK-SYNC] Set Airsoft742's nickname to Airsoft742.
Server: Welcome back, Airsoft742
..................................................................................
That's when i deleted the database file in the OKB3 Directory, as someone posted that it solved this error, and synced myself
After that i re-synced to see if it was working, and then the server became un-responsive again

Please provide any additional information below.
