wrong vmstat graph on centos 4.3 (RHAS 4.3 )

I have 4.2-RC-20060712 server & client running on two CentOS servers. The local client on the server has it ok for its vmstat graph (user/sys/idle is reasable and sum up to 100%). The remote client's vmstat obviously was reading some bogus data. I left CLIENTOS= commented out in /etc/default/hobbit-client. read some old posts regarding RHL 9, whose vmstat has 'r b w' instead of 'r b' as seen on RHEL4. any idea what CLIENTOS= I should set it to? I tried to purge the vmstat rrd for that client and it came back still bad.
