Hi, friends! This problem occurs periodically, not so often. Who is right and who is wrong, i could not understand. Kodi? PVR addon? TBS drivers? Kernel? Please see logs.

Please provide a Tvheadend generated log see Traces and Debugging. Additionally, What OS and version of Tvheadend?

Debugging not enabled at this time and i don't know when the error will appear again, but this error will appear, because it happens periodically. Probably this happens at a large Kodi uptime. My system is Arch, kernel 4.9.65 LTS, TBS6904, v4l-dvb-git-r908.48b0842. Debugging enabled now, time has gone... After restarting tvheadend daemon all worked as expected.

tvheadend-git 4.3.r1529.gc8bbae504-1 (latest)

Илья are you use AUR?

# tvheadend -v
tvheadend: version 4.3-1529~gc8bbae5

there are regular and debug package
during crash debug one report source code location of error

i learned just Basic and can program Industal automation aka robots

I don't think it's related to the TBS card because I have the same messages with FritzBox 6490 as a Tuner.

2018-11-03 19:49:06.730 [WARNING]:mpegts: too much queued input data (over 50MB) for SAT>IP DVB-C Tuner, discarding new

I have Tvheadend 4.3 running on a Debian 9 VM inside ESXi. Main Client is a Kodi x86 PC.

From my experience this looks like tvheadend is getting "stuck" somewhere.
When that happens you get this message "mpegts: too much queued input data (over 50MB) [...]" (tvh is locked somewhere and stops processing input data).
And that's why Kodi complains with "No response received" (tvh stops responding to requests - and I bet that the webui is also "dead")

Your uploaded tvh log is short (we can't see what happened before getting stuck).
Please post a "better" tvh log and/or explain what conditions lead to this problem.

BTW, which TBS drivers are you using - mine or the closed source ones?

Who do you mean? I have only one client and I was watching the same channel while logging.

Run tvh with the log options, watch one channel for 60 seconds, stop tvh.

hi. Same issue with internet radio stream.

2018-11-19 14:42:59.718 config: unkown subsystem 'parsers'

It will be right 'trace --parser'

You have to upload a log where we can see the issue happening, not just a log of 60 sec running tvh...

No 'TRACE' lines, read again https://tvheadend.org/projects/tvheadend/wiki/Traces

No "DTS and PCR diff is very big" lines in log. Please, think about what are you trying to report.

This problem occurs periodically, but not so often. Need time to wait for...

Problem does not occur instantly after 60 seconds, it sometimes takes hours.

Please, add 'pcr' to the log (--trace pcr,parsers). Anyway, it seems that the ffmpeg pushes the wrong PCR clock to the output stream (tvh uses those clocks to drop the invalid packets). It might also help to save the original MPEG-TS stream which received by the tvheadend (capture it using the passthrough MPEG-TS profile) to check the MPEG-TS timestamps.

Event "too much input data" need to be direct connected to restart service action.

At this point, I can't restart tvheadend, the service does not respond anymore. I have to forcfully kill it.

@Daeniel, parser traces are missing. --trace pcr,parsers

I can not log parsers: unknown subsystem "parsers".

It seems like a ffmpeg problem. There's PCR mismatch starting since 2018-11-27 11:03:40.476:

In what system you're running tvheadend?
It seems that it's too slow and can't keep up... or tvh it is really hanging.

To debug a hang, you can try the latest code: start tvh with "--thrdebug 10020"
It should tell you where it hangs.

Tvheadend is running inside a Debian 9 VM on ESXi with a Hypervisor which has a Intel 4th Generation i5 with 16 GB RAM. Raw Horsepower is not the problem here.

Will try the thrdebug command next time.

It looks like that the key update is invalid (wrong key) and the garbage is not parsed correctly by the tvh's elementary stream parser, but it's just a guess.

With "key" you mean decryption key from oscam? Because I also have the same problem on unecrypted channels.

Ok, then it's something different.
