MBP Running Slow - Related to Transmission?

[zmbras]

My MPB has been running slow recently and crashing during the past couple of days, so I opened up Consol to see what was going on and to my suprise found this message more than 4000 in the 2 hours since I booted up:
2/8/12 10:49:15.000 AM kernel: Length of address is greater than what will fit in info structure
I set out to find the root cause, and after shutting down applications one by one, I figured out it was Transmission. When Transmission is not running I don't get this message once over two hours, but as soon as I start it up, it begins happening 4-5 times per second. I don't know what it means, but it doesn't seem like it could be good. It does seem that my MBP is running faster with Transmission closed (could be speculation, I know). I like to keep transmission open all the time to seed and download, but if I have to sacrifice processing speed for that, I'm afraid I won't be able to make that trade. Any ideas or suggestions? Here's a screenshot just to illustrate:
