Please post what Operating System and version you are running and what Shell you use.
Please post relevant detail about your hardware. Like is it the latest Cray or an old PC? I have seen sar give misleading figures on a very fast computer and (more likely) on a very slow computer.

Please post:

df -k /
df -k /usr
df -k /var

Is this a single-processor system, a Virtual Machine or what?

thanks for the reply.
Its not happening everyday. Its only unpredictable.

Its a stand-alone box with following configs:
system:

%wio is not reported in Solaris 10, so that column is no problem.

Sorry for the partial answer.
