what mobo/chipset do you have? and what kind of ram do you have? do you have any constantly running apps in the background (like little snitch)? at this point i've given up on finding a solution, and i just want to know what common link divides those of us who are having these issues from those who are not. there has to be an answer.

for me, a sure-fire way to get the system to start acting strange was to run torrents with little snitch turned on. so i turned off little snitch and started downloading a torrent, and so far i've been running for 10 hours without an issue. additionally, i've only seen ONE mDNSresponder "tick" error since. normally i would have seen about 10 by now. that's all i've got to say though i'm sure this problem will return in some way or another.
