Server Version#: 1.27.2.5929
On my QNAP 451+ running today’s stable PMS on QTS-4.5.4 Build 20220419,
I realized I hobbled my Plex system by disabling deep analysis on scheduled tasks.
When I opened a SSH terminal and tried from the command line, the Scanner crashes.
A quick guide:
[https://support.plex.tv/articles/201242707-plex-media-scanner-via-command-line/](https://support.plex.tv/articles/201242707-plex-media-scanner-via-command-line/)
**What I Did as admin:**
```auto
$> uname -a
Linux TheRAID 4.14.24-qnap #1 SMP Tue Apr 19 01:51:20 CST 2022 x86_64 GNU/Linux
$> echo "$(getcfg system version) $(getcfg system 'Build Number')"
4.5.4 20220419
$>
```
**I found that help works:**
```auto
$> "/share/CACHEDEV1_DATA/.qpkg/PlexMediaServer/Plex Media Scanner" --help | head -n4
Plex Media Scanner (c) 2010-2020 Plex Development Team.
-h, --help Display this message.
-v, --verbose Show more output.
```
**The Scanner Crashes**

Would anyone like the dmp file in a PM?
As soon as I see that **libc++** my eyes sort of glaze over. \>.\<

Check your usage:

thanks it works now. I wasn’t aware of setting that environment variable.
Can we get it added to the Article or should I have known?

I looked at the documentation.
It does already state about setting up the environment.
It seems to be well known already, knowing you can move the Application Support Dir anywhere you want that you’d need to tell the scanner where it is.
Linux NAS systems expressly set this per vendor.
Linux PMS distros also do the same in /lib/systemd/system/plexmediaserver.service.
I’ll submit a request for change if needed but think, and maybe it’s just me, that we Linux users should know how to figure out what needs to go where.

Thanks! Right under Linux in the Scanner article it says to set my environment,
and I was able to find other posts about that variable. Darnit.
