Thanks, I wasn't sure if it was a kernel issue at first (which is why I posted here instead of filing a bug). But it took out a production server in the middle of the day, and I was out of the office, so I had to just shut-up-and-fix-it quickly. I've since upgraded to a newer kernel and everything looks OK, but the issue only showed up after around 5 months of uptime. If I go another 5 months without an upgrade or reboot, maybe I'll find out if the issue is reproducible =)
