I asked this on the users list but didn't get a response. Maybe you guys can help.

When I do "xm dmesg", I see a number of errors like these:

I'm not positive, but they appear to coincide with a lot of block traffic. Otherwise the system seems to work, although has erratic slowdowns. Is this bad?
