I haven't got that problem and I didn't type any command into a console.
But well this will be fixed in the next wallet update I hope.

Do you use windows 7 or mac or Linux etc?
Might just be related to an OS, might be fine on XP, all I know is that I had the problem quite early on, posted about it here quite early on too, was basically as soon as my wallet could start to stake coins, my computer was getting slower and slower and then noticed my hard drive was out of space. Found that my debug.log was huge for banksycoin and then went and read on some other threads here trying to find something that was similar. Found a fix for it by putting that line in the banksycoin.conf and that stopped it from growing huge again.
Could be based on how many transactions you have in the wallet, I just do not know...
