Tvheadend crash while scanning skyuk muxes
Added by Bo Byskov about 9 years ago
Hi,
Just installed Tvheadend (4.1-645~g46c82a8) on our debian server, and added the pre-configured SkyUK muxes.
Scan is running fine for a couple of min., but then crashes and spits out the following msg.:

Segmentation fault
I tried to mesh with the bouquet options, and did a clean install of tvh, but both without any luck.
Could this be a bug in tvheadend, or have i missed something ?
If you can reproduce this please run Tvheadend under gdb, see Debugging & Traces. Once you have the logs please create a new issue (include a ref to this forum post).
Have you tried just adding 11778000 V 27500000 2/3 instead of using predefined muxes? That should find all active transponders provided you have Network discovery enabled, be sure to delete all your current muxes.
I was able to reproduce the crash with the "11778000 V 27500000 2/3" mux under gdb, and have collected some debugging informations. I'll create a new issue and post the log/debug files with it.
On a side note, i added just the 11778000 mux, being the only mux in tvheadend on a fresh installed tvheadend server, and it was scanned without any problems. Since the network discovery was enabled, a bunch of other muxes appeared. The next mux in line for scanning was 12324000 V 29500000 3/4 and everything was looking promising, but it unfortunately crashed and with the same output as before saying : bouquet: new bouquet 'BSkyB Bouquet 13 - Test: London'
I don't know if the "new bouquet" has something to do with tvh crashing, but it kinda looks like it 
Okay
Remember to include what bouquet you used, your hardware & anything else you might think is relevant no matter how small.
