I'm running 4.11 with all current patches applied.
I hadn't changed any config files in ages, and this suddenly started
happening on Sunday afternoon. It seems to go down about every hour or so.
Not much suspicious looking in /var/log/messages... at the moment I'm tempted
to suspect my memory has gone bad...  ?

One thing against me is that the box is an hour drive by car (in Tsukuba) and
I have to keep calling the people there to ask for reboots, which they are
starting to get tired of. My attempt at a temporary solution to that is
having written a cron job to reboot the server twice an hour... pathetic, I
know, but...

Scratching my head,

Shawn

PS: I also check my mail on said machine, so mail to this account bounces
when the box is down... :-( !
