Description kb 2008-06-14 08:26:30 UTC 
Description of problem:
After making a fresh F9 installation the poor computer swaps (or reads/writes)
to/from the hard disk so much that the computer stops responding for minutes at
the time.
This repeats more or less every 15-30 minutes and more often if the computer is
recently restarted.

my guess is that there is some indexing service running, but it's not showing up
on in the top command output, it is probably very low on CPU.

perhaps all indexing services should be much less aggressive in the future.

and if you have an idea on which service could cause the problem, please write a
line. 





How reproducible:
Install fedora 9.

  
Actual results:
computer reads(/writes) disk like crazy, even when there is are other
applications running.

Expected results:
When no applications use the disk, the OS should not do anything on the disk, or
very little.

sorry for changing the severity.
but this problem really makes the computer useless.
i just sat around and waited for 20 minutes for the OS to calm down.
the disk operations are still running a lot but at least i can type something on
the machine.

please let me know if i can help you in any way.
perhaps there is a top command for the disk read/writes that i could issue to
find out which processes read/write the most?

Try iotop.  We can't really fix your issue without knowing what process you're
seeing cause the disk I/O.
Comment 3 kb 2008-07-14 18:21:23 UTC 
thank you a lot for the info on iotop.
This bug may be closed and rejected. After a few days of testing only one
application stood as the possible problem, firefox.

hence i will file a bug there and again apologize here.
