Thanks, I wasn't sure if it was a kernel issue at first (which is why I |
18 |
posted here instead of filing a bug). But it took out a production |
19 |
server in the middle of the day, and I was out of the office, so I had |
20 |
to just shut-up-and-fix-it quickly. |

I've since upgraded to a newer kernel and everything looks OK, but the |
23 |
issue only showed up after around 5 months of uptime. If I go another 5 |
24 |
months without an upgrade or reboot, maybe I'll find out if the issue is |
25 |
reproducible =) |
