scan status always on idle pend

Markus Buech

a few days ago my sat/ip receiver crashed and disappeared from tvheadend. after rebooting it came back.
but since then the scan status of every mux is "idle pend". what's the exact meaning of this? i know what "idle" and "pend" means, but "idle pend" is not clear to me.....
this leads to the muxes being scanned forever without any pause and the number of muxes left to scan under "network" does never count down
how can i fix this? i don't think that this behaviour is desirable because the tuners are always under load this way....

Markus Buech the scan status of every mux is "idle pend". what's the exact meaning of this?

Reading the source code didn't help much:

  MM_SCAN_STATE_IDLE,     // Nothing
  MM_SCAN_STATE_PEND,     // Queue'd pending scan
  MM_SCAN_STATE_IPEND,    // Queue'd pending scan - idle queue
  MM_SCAN_STATE_ACTIVE,   // Scan is active

Have you tried to set the mux to 'Active'? That should force a scan and hopefully go back to 'Idle' when its finished.

Markus Buech

Yes I already tried that but it does not help. The mux seems to be scanned when set to "active" but after that it changes right back to "idle pend"

Markus Buech Do you have "Idle scan" ticked in your tuner settings?

Markus Buech

Yes but unticking it and saving doesn't change anything...

Markus Buech

For testing I turned off everything that is epg related (like tuner settings and epg grab) and the status still says "idle pend"...
I don't know what else to try

Markus Buech I don't know what else to try

I was able to reproduce this by going into Configuration -> DVB Inputs -> Networks and enabling Idle scan muxes:.

From the help text:

Idle scan muxes : When nothing else is happening Tvheadend will continuously rotate among all muxes and tune to them to verify that they are still working when the inputs are not used for streaming. If your adapters have problems with lots of (endless) tuning, disable this. Note that this option should be OFF for the normal operation. This type of mux probing is not required and it may cause issues for SAT>IP (limited number of PID filters).

Enabling this setting worked immediately, however, to disable this, I needed to both disable the setting and also restart TVH.

Markus Buech

That did the trick, thank you very much!
I can't recall ever having enabled that setting, but obviously I have....
