Description Robert J. Osborne 2002-09-18 19:25:13 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020715

Description of problem:
An unsigned long is tested against being less than zero, causing gross
inaccuracies in idle percentage in top during heavy loads when the variable
"wraps" to a very high value.

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1.Start top
2.Build several things, put a high load on slow processor system, etc.
3.Observe occasional in-excess-than 85000 % idle on top (single processor,
calcuation would be different for SMP boxen)
	

Additional info:  top.c diff file should be attached against procps-2.0.7

Comment 2 Alexander Larsson 2002-09-18 19:31:56 UTC 
I think this bug is fixed in rawhide with the procps-2.0.7-idlebackwards patch.
