Red Hat Bugzilla – Bug 118352
(VM) setfiles exhausts available memory
Last modified: 2015-01-04 17:05:00 EST
Description of problem:
When running 'make relabel' on a drive with large numbers of files
(150000) setfiles eventually consumes all available memory and begins
to swap. It eventually uses all swap and hangs machine
Version-Release number of selected component (if applicable):
every time on my x86_64 box
Steps to Reproduce:
This looks like it might be a kernel problem.
The app is not growing but free memory is dropping.

Memory seems to free up when the app exits.

kernel messages when running out of memory running setfiles
This is using kernel 2.6.3-2.1.253 on x86-64 box
I've looked into this on i386 and have not observed anything unusual
(e.g. memory pressure reclaims dcache, ext3 inode cache slab entries
Can you please test with the current Fedora kernel?
If you still see the problem, are you able to duplicate it on an i386 box?
This looks a lot like the updatedb problem report. You might want to
try Arjan's latest and greatest
still a problem with the 2.6.9 updates ?
Haven't experienced for some time, if it occurs again I'll reopen or
file a new one.
