(Get the code!)
Julien,
it seems that kernels 2.6.18 to 2.6.21 have some serios issues with
heavy disk io especially when multiple processes are fighting over
io and if read and write are going on in parallel ...
for us the upgrade to 2.6.22 helped a lot ...
there were changes to the io schedulers and massive changes to the
default values of the /proc/sys/
we also found that the problems were more pronounced when using lvm
... unfortunately this is all anecdotal and non conclusive.
so if you have the chance, you might want to try 2.6.22 ...
cheers
tobi
