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:
Code:
df -k /
df -k /usr
df -k /var

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

Its not happening everyday. Its only unpredictable.

Its a stand-alone box with following configs:
system:
System Configuration: Oracle Corporation sun4v SPARC T3-1B
with 128 virtual CPUs + 16GB Memory

OS & Firmware:
SunOS <hostname> 5.10 Generic_147440-09 sun4v sparc sun4v
Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC
Sun System Firmware 8.0.1.c 2010/11/02 17:35
OBP 4.32.1 2010/10/13 18:23

$ df -k /
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d3 24787053 14145264 10393919 58% /
$ df -k /usr

Thanks.

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

Sorry for the partial answer.
