If the connection with streamproxy (transcoded stream) is not so stable (or to slow) and the client (for example VLC) reconnects a few times streamproxy process for given session is not finishing. So even the client has disconnected for good, there are 2 streamproxy processes (there is one initially when there is no streaming at all). Further connections are not possible (VLC gets errors). If I killall (etc/init/d/streamproxy.sh stop) streaproxy stb totally hangs. No more connections (even ssh) are possible. The only way to get it working is to turn off/on. I assume kernel crashes.

 

I observe it both using VLC on Windows, Android VU+ Player. It happens after switching transcoded channel a few times. I can even replicate the problem on LAN. I need just to use android player and kill it so following connections are not possible. Restarting STB from ssh (reboot)  hangs the device also (the same result as just killing  streamproxy. These "orphan" streamproxies seem to lock recording (and transcoding) on the last selected channel and killing such process leads to total system hang (freeze).

 

OpenPLI 4, fully updated. The issue has been occurring since I installed OpenPLI (more than month ago).

This is a known problem, the driver crashes, have a look at the dmesg output. You will have to reboot to fix this condition.

We're not starting building workarounds for bugs in drivers... (there would no end to that). You could do it by yourself though, make a script read the kernel log and if it shows the kernel oops (try for the exact string to match), reboot.

I'm not sure if any script is being run if kernel crashes.

LOL...

 

It's not the kernel that crashes, it's the transcoding engine only.

But after this crash i cannot connect to stb using SSH. Remote doesn't work too. I have to use switch off/on to fully restart the device. Can you advice how to manage this situation automatically?

I have the exact same proble with my ET10k. I tried connecting with telnet and reboot but noting happens. Only solution is to swich the device off and on manually.
