Re: Total crash of my db-server

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
