This is a multi-part message in MIME format. --------------54766DDCCA7C1DB7B3CF135E Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Just an update on status. I did three things: Disabled ASLR in /boot/loader.conf kern.elf64.aslr.enable=0 kern.elf32.aslr.enable=0 I did this b/c I read that in 13.2 it was automatically enabled. I also set a flag to control the growth of the ARC vfs.zfs.arc_max="4294967296" finally, since I have multiple jails, I wondered if something had changed that would make old userspace binaries a problem. So I upgraded all jails with ezjail. The net result is that the host is up since about the 20th of the month. Thank everyone who took the time to respond to my ask for help. > Graham Perrin <mailto:grahamperrin@freebsd.org> > July 15, 2023 at 9:49 AM > > On 13/07/2023 01:22, Tom Everett wrote: > > I should not treat freebsd-update as a sane approach to downgrading. > > Instead, if downgrade is essential, build from source. > > On the releng/13.2 branch > <https://cgit.freebsd.org/src/log/?h=releng/13.2>, tag release/13.2.0 > (preceding patch 1) is at: > > <https://cgit.freebsd.org/src/tag/?h=release/13.2.0>; > commit aab15c8d11a299cc11fd1d1cd09aec11383c99bc > <https://cgit.freebsd.org/src/commit/?id=aab15c8d11a299cc11fd1d1cd09aec11383c99bc>; > > Tom Everett <mailto:tom@khubla.com> > July 12, 2023 at 6:22 PM > Well, it may be time to downgrade.
