tracker-store leaks memory on my system, and after approximately 1 day of uptime, it'll leak everything and send my system into a lockup. The kernel out-of-memory (OOM) killer isn't going to do anything, and I'm not sure if
earlyoom is going to help either. This means the simplest solution is just going to be:
1 2 3 4
while true; do pkill tracker-store sleep 3h done
If I had to do this with Firefox or Chrome, this would be a bit too extreme, but since
tracker-store is only supposed to run in the background anyway, I don't mind (or care) if it's getting killed.
So, also wanting to learn systemd timers, I wrote a timer that does what the above script does.
The service file (
1 2 3 4 5 6 7
[Unit] Description=Kill tracker-store [Service] Type=oneshot ExecStart=/usr/bin/pkill tracker-store SuccessExitStatus=0 1
Exit status 1 from pkill means the process couldn't be found.
The timer (
1 2 3 4 5 6 7 8 9
[Unit] Description=Kill tracker-store [Timer] OnBootSec=15min OnUnitActiveSec=4h [Install] WantedBy=timers.target
systemctl --user enable --now kill-tracker.timer to enable and start the timer.
