Set htop as this

result must be something as this

Thank you Saen.
I have to wait for the error to occur. I don't know how to provoke it.

Finally...

Let me guess, you have one tuner and network with more then one frequency's,
and client's with want different frequency's in same time.

7 HD streams

hmmm! Is that what is happening? I don't understand how it can be. As I said, Tvheadend's clients are Kodi, from the pc connected to the tv, VLC from a pc on the local network and, occasionally, a mobile phone, through the browser, but the only claimant is me, that is, there are never 2 instances at the same time, I don't even think I asked for 7 consecutive broadcasts, although it could be that I did it trying to cause the error. Why could this be happening then?

I configure Tvheadend using a Github script that includes Mux, services and EPG, I have been using it for a long time without problems. I only have one user * admin configured. I doubt that someone is accessing my network. The only thing I can think of that could happen is that the requests are not canceled and are always active, although the problem occurs quite some time later, when I am not requesting anything from Tvheadend. Also, when the error is occurring, the Tvhedend webif shows no signs of activity.

What show status and logs inside TVH WEB-UI

On user "*" can allow only access from you lan
ex:
if router ip is
192.168.1.1
allow access from
192.168.1.0/24

from outside make other user

Ok!
I just started Tvheadend and directly the error has started.
Tvheadend webif during the error:

htop during error:

Attached Sys.log from last start of Tvheadend.
P.S. I do not need to use Tvhedend from outside the local network, I understand that it is not necessary to create a new user.

In the start of Tvheadend that I showed in the previous comment, "initial scan" was enabled, it is not usually like that, sorry if it may have caused confusion. After disabling it, I restarted Tvheadend and waited for the error to occur again. From then until the error occurred this is what the Sys.log recorded.
If I knew what the relevant information was, I would select it.

Disable all unused EPG modules.

There is only one module enabled

Yesterday the problem never occurred, today it seemed that it was going the same way, I was beginning to think that it had been solved, but... it happened! I think if Syslog reflects it he should be on these lines, starting at 12:04:57 and until I restarted Tvheadend at 12:18:02.
Any idea what is happening in this interval?
Thanks.

Is this difference in CPU consumption normal?

Tvheadend Player:

VLC:

Disable external EPG and use internal NOW/NEXT.
Set extarnal EPG to be downloaded once on 24h.

Thank you saen.
That's where the conclusions I was coming to after yesterday didn't have that high CPU usage even once: Maybe, when switching from minisatip to traditional mode, "EPG over the air" was activated and being the disabled modules would cause the problem. When it happened again today, my approaches have been broken. Yes I am going to remove the EPG refresh for 3 times a day, it is unnecessary, I may leave it as default or even remove it completely to see if that solves the problem. I suspect that indeed it has something to do with the EPG. You too?

Edit:
I do not know. I have now put the retransmission of Fómula1 with VLC and the CPU has risen (I don't know if the EPG is involved in this). After restarting Tvheadend the CPU returns to a minimum consumption.

Well, it seems that the problem has been solved: that high usage of the CPU has not occurred for days. The point is that, as is often the case in these cases and having made more than one change, I don't know exactly what has solved it.

Since I suspected that the problems came from the EPG, instead of installing it through a script that configures everything, I did a manual setup from scratch. I doubt that this was the solution, because with the script it had always worked correctly.

I think the problem was in the existence of 2 ".hts" folders; the one corresponding to my old installation in the address "/home/user folder/.hts" and the one that had been created with the updates in "/home/.hts". First I renamed the old one to ".hts.old" and then after a while I removed it and the problems disappeared, I understand that, for some unknown reason, both configurations interfered and generated the problem.

I would still like to know if the high CPU usage by Tvheadend player compared to VLC is normal.

Greetings and thanks for the help.
