Description Chris Eddy 2002-11-09 17:02:15 UTC 
Description of Problem:
vmstat displays insanely high values (eg: 21262213, 21474835) when time interval
is set to 1 second.

Version-Release number of selected component (if applicable):
vmstat -V returns: procps version 2.0.7


How Reproducible:
For me, extremely.  On a continuous run at 1 second intervals, the problem
occurs on about 2 - 4 lines between printing of the column headers.


Steps to Reproduce:
1. vmstat 1
2. 
3. 

Actual Results:
