It's because of last version of wallet. It's filling debug.log very quickly so it is possible to fill your hard up. Restart the daemon and debug.log will start from 0.
Ah, thank you so much! I will destroy that debug log, LOL. Actually, it could also be because I was running a testnet masternode... I'm gonna try expanding my storage, wonder how much that will cost? Maybe the cost will be offset due to Evan's sleeker communications, which should have reduced my band width??
