I'm getting the same type of errors for a box that's been keeping
current on 4.9 (and the 4.x tree) for the past two years. The box had
been relatively stable up and until late December, when in January and
all through February the box has been rebooting on a regular basis.
This is a dual-proc box with 256 MB of ram. I'm running a pretty
balanced combination of web and mail server on it. The load used to
(and with some tuning) stays below 1.00 load, but I've seen it get to
above 3.00 and start crashing. I had it at 80.00+ before without it
dying before, so I'm betting there's some code instability.
I'd be willing to work with any developer on the list to test code to
get this condition mentioned here in the thread solved.
(On a side note, to inspire some quicker work, we host Howard Shore's
website, the one who won the music Oscars last night on Lord of the
Rings, and I would be grateful for any help to keep the site stable)
P.S. - the unmounted filesystem error below is after one of the crash
reboots.
