And you made comment of this on the list? Including the specs. Most 
problems I hit with different 2.4 kernels were problems with 2.4 itself.

At work we have a database box with 10GB+ Progres 9 databases on it which 
has been running just fine. I have also experienced one corrupted fs on a 
squid cache which caused recovery to cease after a crash. That was fixed 
with xfs_repair and I have seen problems with squid caches before.

The production boxes are all running the 1.0.2 release kernel. Those 
kernels are originally Red Hat kernels which include fixes for a lot of 
known bugs which have not been fixed in -linus and also include a whole 
bunch of drivers for otherwise unsupported but neccesary hardware. They 
have also been heavily regression tested.

Most stuff I just think up myself. I look around what programs I have and 
just run a lot of them simultaneously.

The amount of damage I have personally seen on a XFS fs was caused by 
something between the keyboard and chair. (eg. me)
