On an up-to-date CentOS 7 system, I am running named-sdb (pulling domain records from MySQL), which is segfaulting randomly (after 3-8 hours or so it appears) in libmysqlclient (I’ve opened a bug).
Since this is an internal service, until the segfault can be addressed, I wanted systemd to restart it for me. I created a file called
in it. I did “systemctl daemon-reload” and restarted the service, but systemd is not restarting it. It knows it died, because that’s in the log (and it ran the chroot cleanup service):
Aug 25 12:03:39 dnssql systemd: named-sdb-chroot.service: main process exited, code=killed, status/SEGV
Aug 25 12:03:39 dnssql systemd: named-sdb-chroot.service: control process exited, code=exited status=1
Aug 25 12:03:39 dnssql systemd: Unit named-sdb-chroot.service entered failed state. Aug 25 12:03:39 dnssql systemd: named-sdb-chroot.service failed. Aug 25 12:03:39 dnssql systemd: Stopping Set-up/destroy chroot environment for named-sdb… Aug 25 12:03:39 dnssql systemd: Stopped Set-up/destroy chroot environment for named-sdb.
I see the file listed in the output of systemd-delta, so I know it is being seen. Any idea why systemd isn’t restarting it?
