Re: openbsd under heavy load corrupts fs and crash ?

[Per-Erik Persson <pere@fos.su.se>]

Thanks a lot everyne for your suggestions, especially the obvius crash 
man page!

After analyzing the data in a calm and quit environment I found out the 
common thing on the machines.
Postfix is assuming a lot of things when it moves around the mail.
I really think the OS should be able to handle this in a better way but 
running postfix on anything else than an ext2 filesystem can give you 
problems under heavy load and bad luck!

When I have found a solution for the problem I will let you know.
I saw something about exporting the directories via nfs with option sync 
and mounting them back again, it is a long story.....
