the 2004.07.30 release, DS1 DS2 all has this issue. the
network performance on RHEL3 is 0. because all IO are
failed and thus none io is counted.
dynamo will have high cpu utilization like 99%. so i
guess most io are failed immediately.
not sure if this is because poor support of aio on
network in 2.4.x kernel. under 2.6.x kernel, it is fine.
