Red Hat Bugzilla – Bug 50565
(VM)32 MB system can't handle a compilation
Last modified: 2008-08-01 12:22:51 EDT
When compiling some not-too-big source code on a 32 MB beta3 system (no X
running), the system starts trashing very quickly and doesn't come back
within a reasonable time (at least one hour), so only the reset button
helps. This is fully reproducable.
The same test on the same HW config with RH 7.1 works fine.
This defect is considered SHOULD-FIX for Fairfax.
The problem still appears with kernel-2.4.7-0.3. I'll attach a file with 3
"top" snapshots just before the system stops reacting at all.

Top output of 3 stages before the system stops reacting
Is this the same bug as the one that causes very high inode_cache count in
maybe. I wonder if 2.4.7-0.5 or later behave better with 32Mb
Would like to try, if 0.5 is available somewhere...
ftp://ftp.beta.redhat.com/pub/rawhide/i386/RedHat/RPMS/ has -0.9.1 right now.
BTW, as I mentioned in testers-list, I still see a very similar problem (and see
very high inode_cache count at the same time) with 2.4.7-0.8 on 128Mb of RAM.
Tested with kernel 2.4.7-0.9.1: same problem :-(. And the inode_cache in
/proc/slabinfo stays in the last 10 minutes of the system's life around these
inode_cache 341 711 424 79 79 1 : 15113 38560 2064
I was still having these problems with 2.4.7-0.9.1, but with 2.4.7-0.13.1 things
seem to be finally working normally.
Thanks for testing/confirming this. We'll continue to try to improve the VM, but
without breaking the stability (I hope :)
Kernel 2.4.7-2 (current rawhide) does *not* seem to resolve our problems :-(.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
