Re: Spontaneous PostgreSQL Server Reboot?

Alex,

the answer is "no" to all of these. We are a tiny start-up (2 guys, and
we do our own cleaning); ambient temperature varies significantly but
is not related to the failure, and one machine starts beeping when it
gets too hot (then we added an extra case fan); no fancy watchdogs
(maybe someday... One can only dream :-> ); three different cases,
power supplies, motherboards, etc., etc. (one power supply is
extra-large, and that's the machine that started failing first!).

We originally blamed the problem on hardware failure (first machine);
then on OS version/configuration (second machine); now we're out of
things to blame, except maybe unusually bad luck...

Thanks,

Andrew
