Red Hat Bugzilla – Bug 129629
Top fails to show CPU hog
Last modified: 2007-11-30 17:10:47 EST
Description of problem:
I have been using an RSS aggregator called liferea. Its built with
python. Occasionally, it will go out to lunch and start consuming
large quantities of cpu. Gkrellm and the CPU panel app show the
utilization going up. If I use the top command I see what looks to be
an unused system. It doesn't register what the other utilities see. It
looks like a very quiet and unused system.
Version-Release number of selected component (if applicable):
top uses procps version 3.2.0
When it dies its consistent. Haven't figure out how to cause liferea
to break. So far this is the only program that demonstrates this
Steps to Reproduce:
1. Fire up liferea
2. Wait til CPU starts going up
3. pop open top
Top doesn't register the liferea process consuming all the cpu.
To see the top process being liferea or python, since liferea is
python code. But I see neither
Does liferea use threads ?
If you switch on display of all threads in top, do things work the way
they should ?
should be fixed with the 2.6.10 kernel
