<div>I just upgraded to recent SVN this week (and tried again with this mornings) and mythbackend is running oddly. It starts out fine, then, after 5 to 20 minutes, it starts hogging the CPU to the point where it causes ivtv to flake and throw those write errors, and my log starts filling up with

However, I don't believe it's a straight IO problem, because I can actually load the box more than it was before (watching a movie, while transcoding a DVD with mencoder, while recording, with mythcomflag running on this machine and a slave, and the slave running mythtranscode on it) without the problem recurring. It's the mythbackend process that shoots to 90ish percent CPU though and throws all the errors, not the mythtranscode process.
