tracker-extract high cpu usage

Question

I see that one of the users has a 100% cpu process named tracker-extract. I tried to terminate that based on the suggestion here, however, still I see that it is running. All users have such process but as you can see one of them consumes a lot of cpu.

# tracker daemon -t
Found 1 PID…
  Terminated process 2265 - 'tracker-server'
# ps aux | grep tracker-extract
jafarian 21478  0.0  0.0 728000 11664 ?        SNl  Oct29   0:00 /usr/libexec/tracker-extract
jafaria+ 23002 98.3  0.0 810900 18252 ?        RNl  Nov09 3746:02 /usr/libexec/tracker-extract
jafaria+ 31826  0.0  0.0 917128 21684 ?        SNl  Oct31   3:21 /usr/libexec/tracker-extract

Just killing the PID isn't a solution because it runs again. How to fix that?

Did you run the command in suggestion as root? – Romeo Ninov Nov 12 '18 at 07:28 — Romeo Ninov, Nov 12 '18 at 07:28

You should install tracker-ui-tools via yumfor older versions. For newer version install tracker-preferences directly.

Then use tracker-preferences to switch on/off what you want/don't want.

For more information check this link and this link.

There is no such package. Is it fine to just install tracker-preferences? – mahmood Nov 12 '18 at 07:48
yes, actually tracker-ui-tools is for older versions. – Prvt_Yadav Nov 12 '18 at 07:50
OK I installed that and then logged in as that user and ran tracker-preferences and unchecked the options. Still I see that a process for that user consumes 100% cpu. – mahmood Nov 12 '18 at 08:10

Try to check after logout or restart. Is this one of the process which you check out?? – Prvt_Yadav Nov 12 '18 at 08:14

The processes are started with .desktop files in the /etc/xdg/autostart directory.

[user@host autostart]$ pwd
 /etc/xdg/autostart

[user@host autostart]$ ls -lrt tracker*
 -rw-r--r--. 1 root root 5954 Sep 28 01:27 tracker-miner-fs.desktop
 -rw-r--r--. 1 root root 5234 Sep 28 01:27 tracker-miner-apps.desktop
 -rw-r--r--. 1 root root 4635 Sep 28 01:27 tracker-miner-rss.desktop
 -rw-r--r--. 1 root root 4880 Sep 28 01:27 tracker-extract.desktop
 -rw-r--r--. 1 root root 5474 Nov 12 08:02 tracker-store.desktop

So to disable tracker we will copy these files to our ~/.config/autostart directory and add Hidden=true. This will stop them from loading when we log in.

[user@host autostart]$ pwd
 /home/user/config/autostart

[user@host autostart]$ cp -v /etc/xdg/autostart/tracker* .
 '/etc/xdg/autostart/tracker-extract.desktop' -> './tracker-extract.desktop'
 '/etc/xdg/autostart/tracker-miner-apps.desktop' -> './tracker-miner-apps.desktop'
 '/etc/xdg/autostart/tracker-miner-fs.desktop' -> './tracker-miner-fs.desktop'
 '/etc/xdg/autostart/tracker-miner-rss.desktop' -> './tracker-miner-rss.desktop'
 '/etc/xdg/autostart/tracker-store.desktop' -> './tracker-store.desktop'

[user@host autostart]$ for FILE in $(ls tracker*); do echo "Hidden=true" >> $FILE; done

Now, let's kill the daemon, and delete the old cache files.

[user@host autostart]$ tracker daemon -k
[user@host autostart]$ rm -rf ~/.cache/tracker ~/.local/share/tracker

We should be good to go now. I did a reboot and IT IS GONE!

 !ps
 ps -ef | grep -i tracker
 root      2781  2748  0 17:27 pts/0    00:00:00 grep --color=auto -i tracker

Centos 7

Please note:

Install tracker-preferences as root yum install tracker-preferences

Run tracker-preferences as normal user Set everything off (or leave whatever you think you need).

Reboot

System is nice again after that :))

And then it came back again. Just when I posted my comment tracker-extract came back to live consuming 100% CPU. All I can think off is running tracker daemon -t after each boot. As a normal user. That seems to kill it. – Johan Jan 25 '19 at 08:49

I forgot to uncheck Enable for initial data population in tracker-preferences. It is ok now. Gone. I think. Because I saw tracker-extract pop up and die just now. k for me, I can always use tracker daemon -t if necessary. (For less experienced users something like this is enough to take the PC to a repair shop). – Johan Jan 25 '19 at 09:11
And now tracker-extract is back in full force, 100% CPU. – Johan Jan 25 '19 at 09:12
Last comment. I let the PC run for 2 days straight before and tracker-extract was still running. To me that looks abnormal. I have a lot of files but not that many. Also maybe an idea to use nice for tracker-extract so it does not stop you from using the system. Case closed. – Johan Jan 25 '19 at 09:16
Very last comment. See https://access.redhat.com/solutions/3364861 Redhat secret. Even with tracker disabled it all comes back to live again after a while. – Johan Jan 25 '19 at 09:33
Extreme measure for Die Hard. crontab -l * * * * * tracker daemon -t save Gone (crontab -l as user, not root) – Johan Jan 25 '19 at 09:54
crontab -e * * * * * tracker daemon -t Save (not crontab -l) – Johan Jan 25 '19 at 09:58
Thanks for your effort. Please make sure that the idea is working before posting. Thanks. – mahmood Jan 25 '19 at 11:45
It is working fine Mahmood. Sorry for all the posts. Each time I thought I had the answer it looked good and I reported that. Then it came back again. – Johan Jan 26 '19 at 02:17
