Problems with grsec/pax and swap ?
Posted: Tue Oct 04, 2005 1:08 pmHello,
i have just a short question regarding grsec,pax and swap space.
My system is setup with a kernel raid1, exactly like described here:
http://gentoo-wiki.com/HOWTO_Gentoo_Install_on_Software_RAID_mirror_and_LVM2_on_top_of_RAID
Except for the fact that my swap is NOT on a RAID partition, i use a swap partition on each drive with same priorities defined in /etc/fstab.
(Like /dev/hda2 none swap sw,pri=1 0 0 and /dev/hdc2 none swap sw,pri=1 0 0)
The kernel i run: hardened-2.6.11-r15 (Gentoo kernel)
In this post you can find my configuration regarding the grsec, pax extensions:

My problem is now that every time the server starts using the swap or is about to go in there, the server freezes completly (you can not even use CTRL+ALT+DEL to reboot). Can it be possible that a grsec or a pax option in the kernel configuration causes that behaviour ?
