Subject: [gentoo-hardened] Kernel related bug?
Date: Fri, 09 Dec 2005 01:52:16
Message-Id: 200512090249.57880.johnmiller@email.it
1 I am attaching inline a log appeared on my system while it was a bit loaded.
2 I looked at it because the program "w" segfaulted two times.
3 After than this, the system remained up and running without any problem.
4 Here it is the kernel I use:
5 Linux praisenet 2.6.13-rsbac-rsbac #2 Mon Dec 5 17:06:35 CET 2005 i686 Pentium
6 III (Katmai) GenuineIntel GNU/Linux
7
8 I have Pax and some RSBAC modules compiled in, if requested I may attach my
9 configuration.
10 Should I send someone else this log too?
