Hello,
I witnessed a case with Shepherd 0.8.0 on ‘core-updates’
(7b07852ddb334c92bcef69666f21c599f1f0fa79) where shepherd exited all by
itself, all of a sudden. Here’s what /var/log/messages shows:
--8<---------------cut here---------------start------------->8---
May 7 09:36:23 localhost vmunix: [ 20.316829] shepherd[1]: Service user-homes has been started.
May 7 09:36:23 localhost vmunix: [ 21.319625] shepherd[1]: Service nscd has been started.
May 7 09:36:23 localhost vmunix: [ 21.321029] shepherd[1]: Service guix-daemon has been started.

May 7 09:36:52 localhost shepherd[1]: Service xorg-server has been stopped.
May 7 09:36:52 localhost shepherd[1]: Service console-font-tty2 has been stopped.
May 7 09:36:52 localhost shepherd[1]: Service term-tty2 has been stopped.
May 7 09:36:52 localhost shepherd[1]: Service upower-daemon has been stopped.
May 7 09:36:52 localhost shepherd[1]: Service elogind has been stopped.
May 7 09:36:52 localhost ntpd[482]: ntpd exiting on signal 15 (Terminated)
May 7 09:36:52 localhost syslogd: exiting on signal 15
--8<---------------cut here---------------end--------------->8---
The end result was a kernel panic with exitcode=0x100 (meaning exited
with 1).
It looks as though one had run ‘herd stop root’.

It could be related to this bug[1]. The problem is that on 0.8.0 a
process restart can cause a root-service stop.
On your log, I can't see a process being restarted, so it might also be
unrelated.

It looks very much the same though: it’s stopping itself, which most
likely happens as a result of killing itself. I’ve merged them, we’ll
see!
