Sundtek Support Forum

I have an update:

I deleted the /etc/ld.so.preload-file and added a file override.conf to /etc/systemd/system/vdr.service.d/ and /etc/systemd/system/sundtek.service.d

The override.conf file contains these two lines:
[Service]
Environment=LD_PRELOAD=/opt/lib/libmediaclient.so

I removed all VDR plugings and other packages related to VDR, except vdr and vdr-plugin-vnsiserver.

With this configuration, the server runs stable and VDR works; i can connect with KODI from a remote PC.
It was running for more than 36 hours without any problem.

Then i restored the file /etc/ld.so.preload which contains only one line "/opt/lib/libmediaclient.so" and executed "systemctl daemon-reload" (no reboot); after a few hours, the same problem happened again.

For debugging, i logged into all 6 local tty-consoles with user "root" on the server directly after booting.
In one console, i ran "htop", in another console i ran "dmesg -w" and some other logs in other consoles.

After a few hours, i noticed the server had the problem. During this time, VDR was in idle mode, no KODI was runnig.
On the local console, the htop output was freezed, but it showed no high cpu or memory usage. In the dmesg output, i had a lot of apparmor warnings with name="/opt/lib/libmediaclient.so", similar like in my first post.
I can switch between these consoles with <Alt>-F1/2/3...
When i enter a command in a console, e.g., "ls", it doesn't respond. But then, after pressing <CTRL>-C, i get the output of the ls command.

Then i deleted the file /etc/ld.so.preload and executed "systemctl daemon-reload", always with <CTRL>-C afterwards. After doing this, the server seemed to operate normal.
I tried to restart VDR with "systemctl restart vdr", but this command did not finish, i had to press <CTRL>-C.
I tried it multiple times and also with stop and start separately.

Then i did a reboot, it took a long time to shut down (several minutes).
After rebooting, i checked the VDR log (journalctl -u vdr).

There you can see some error messages from the failed vdr start before reboot:

So for me i have a solution, but maybe it would be interesting to find out why the servers hangs when the ld.so.preload file is installed.
Do you have any ideas, which logfiles i could check?

Der Tuner ist über 10 Jahre alt, der wurde damals noch von einer Partnerfirma entwickelt, von der wir uns getrennt haben und anschließend die Geräte selber entwickelt haben. DVB-S/S2/S2X wurde erst ab 2018 direkt von uns entwickelt...

Stecke den Tuner direkt an und schau Dir auch die BER an, wenn eventuell hilft auch ein längeres USB Kabel.

Teste mal
/opt/bin/mediaclient --testastra -d /dev/dvb/adapter0/frontend0
/opt/bin/mediaclient --readsignal=10 -d /dev/dvb/adapter0/frontend0

Danke für die rasche Rückmeldung!
Das war exakt die Ursache.
Download klappt nun und (Respekt) klappt out-of-Box mit Rocky 10.

> with "hang" you mean the network connectivity problem?

It's not just a network connectivity problem.
It is also not possible to login on a local console.

I can log in locally or by SSH over network, before the server hangs.
Then i wait until it hangs; when i try to execute a command, e.g. "ls", nothing happens at first, i get no response. After pressing <Ctrl>-C, i get the output of the ls-command.
Starting of other programs is also not possible.

Also, the 'poweroff'-command does not work. The server starts to shut down, but then at some point it hangs and can only be restarted be a a power cycle.

Yesterday in the evening, i uninstalled all VDR plugins except vdr-plugin-vnsiserver. Then i connected with KODI from a different computer and did some testing.

Watching television worked. I started a recording and tried to watch a recorded movie while another one was recorded. In this situation, the problem happened again and i had to restart the server.
It seems, the error is triggered by some actions from VDR, but it also happens after some time when i only startup the server with no KODI client connected.

Hallo,
ich versuche gerade Aufgrund Systemumstellung meinen Sundtek-Tuner mit Rocky-Linux einzurichten.
Jedoch scheitere ich schon daran, dass die Downloads nicht funktionieren.

Könnte mir bitte jemand einen funktionierenden Link für das Installations-Script zur Verfügung stellen?

Danke!
