The machine has been stable so far.

I just noticed these unusual messages in the logs today:

Sep 21 09:04:29 akane kernel: HAMMER: Warning: UNDO area too small!
Sep 21 09:05:00 akane kernel: HAMMER: Warning: UNDO area too small!
Sep 21 09:06:11 akane kernel: HAMMER: Warning: UNDO area too small!

The time corresponds to a rsnasphot hourly run.

I had to reboot this machine for an unrelated problem. We should wait
a few more days to be sure if the patch really fixes think.

I was never able to get more than 5-6 days uptime before.
