I have run into the out of bounds positional data error as well.  I was in the Arena fighting a Rogue. 
I will also post this on the bugtracker page for the devs.  While in the arena in attack mode, I started backing up away from the npc into a corridor, accessing my inventory, then healing postion, and finally was moving the potion to my character. That is when the error appeared.

PC Specs (PC used to create crash)

also, the /patition is for in-game, but what channel:  Main, System, Help?
and do I just type /partition  or /partition I am stuck?

here is a link to a screen-shot after I killed the client and restarted it
