Re: Total crash of my db-server

Dear Justin,

I am not sure whether it's really a hardware problem,
because I have had similar problems with different machines
and different os- and pgsql-versions before... If you
browse the archive you will find postings from me about
crashes and problems the last 2-3 years...

I can only tell, that the mysql-servers we are running
have never had similar trouble - and they are run on identical
hardware and os-types under almost identical load.

Currently, I am running postgres 7.3 on a Redhat Linux
(Kernel 2.4.19). Most important software packages are
always up2date.

Hi Henrik,

This *really* sounds like you have a system wide problem, not just a
PostgreSQL problem.

Can't imagine how moving to MySQL will help with that. ;-)

What Operating System are you using, and when was the last time you
patched/updated it with the vendor recommended patches?

Regards and best wishes,

Justin Clift
