Red Hat Bugzilla – Bug 121686
prelink-0.3.1-2 causing httpd-2.0.49-2 to crash
Last modified: 2007-04-18 13:06:35 EDT
Since I upgraded to prelink-0.3.1-2 on April 20, httpd has crashed
during the cron.daily run several times. Some, but not all, of the
times it has logged these messages before crashing:
[Thu Apr 22 04:03:38 2004] [notice] Graceful restart requested, doing
[Thu Apr 22 04:03:40 2004] [notice] seg fault or similar nasty error
detected in the parent process
The daily logrotate happens around the same time, but I last upgraded
logrotate on February 24, and the problem didn't start happening until
I upgraded prelink, so I don't think logrotate is the problem.
I last upgraded httpd on April 8, so I *suppose* it's possible that
httpd is at fault, especially given the changelog entries for
httpd-2.0.49-2, but it's hard to say that for certain, given that like
I said, the problems didn't crop up until I upgraded prelink.
Have you tried prelink -u'ing (after making a backup copy of the binary)
/usr/*bin/httpd and seeing if the segfault goes away?
I don't think I understand your question. The issue is not that
prelink has corrupted the httpd binary and thus caused persistent
segfaults. The issue, I believe, is that each time prelink runs and
modifies either httpd or one of its dependencies (I don't know
which), one segfault happens a result, but that same segfault doesn't
happen again unless prelink again modifies httpd or one of its
In short, the problem is related to the change in state caused by
prelinking, not to the changes made by prelinking, so prelink -u
won't test or prove anything about it.

Not happening for me anymore.
