Excessive upload bandwidth utilization

[jetson]

Is anyone else having this problem? I have Vuze limited to 80% of my full upload bandwidth. For some reason, after a while, Vuze goes berserk and uses 100%. I look at the torrents I'm seeding and their total is less than half of what's being uploaded. And I know it's not another program because the moment I quit Vuze, upload bandwidth drops to almost nothing.

Did you enabled I2P?  It will be on the status bar with an icon similar to

I2P has it's own bandwidth settings, so it's possible if it's turned on, it may be eating some bytes.
