Dear Maintainer,
running systemctl daemon-reload causes systemd to segfault :
root@host:~# systemctl daemon-reload
Message from syslogd@host at Mar 17 16:41:53 ...
kernel:[ 758.716467] systemd[1]: segfault at 7f8d3e4422a0 ip
00007f8d3e4422a0 sp 00007ffd3c533458 error 15
Failed to execute operation: Connection reset by peer
I have disabled as many services as possible, but still get the error.
I have not been able to reproduce on another machine
Can you reproduce the step, how you got this crash? Did this happen once
or multiple times?
This problem happens every time I run systemctl daemon-reload on this
particular machine. I have installed jessie on another machine and not
been able to reproduce it, but the hardware is not the same.
I have not been able to change the settings on this machine to allow
daemon-reload to work
Once the segfault happens, systemd not longer responsds to systemctl status
Unable to get systemd back into a state where it will respond to systemctl
status without a reboot
This has been triggered by attempting to upgrade some packages (eg. sudo) whose
postrm script calls systemctl --system daemon-reload
If systemd dies, it will freeze and no longer reacts to any requests. So
systemctl status etc no longer working, is expected.
You should still be able to reboot in a somewhat ordered fashion via
"reboot --force"
I will try that next time I am able to
systemd should have generated a core dump as /core.
it has
Please install systemd-dbg and gdb and then run
gdb --core=/core /lib/systemd/systemd
The type "set logging on" and run "bt full" afterwards and attach
gdb.txt to the bug report.
