Tvheadend

Hi,
I'm currently running tvh version 4.2.2-83~gc4950973d, but I updated release 4.2 several times during the last few months.
I'm compiling tvh myself on Debian Stable (currently Stretch) for ages.
Starting a couple of weeks ago (like 3 or so, maybe a couple more) I' m facing what the title says.

I had a autorec for the daily news starting half past seven at a specific channel, that was always OK.
Suddenly tvh started to record 2 instances of the same show, with two corresponding files (duplicates) in the recording folder.

So I deleted the autorec from disc using the webif and recreated it from within Kody Krypton's epg today. But that resulted in 3 instances of the same show, not just 2.

I don't have a clue as to what's going on, but I'd really appreciate that you fix the autorec issue.

Mind you, in this case the 3 (or 2) instances of the same show are recorded at the exact same time.

I've been having another autorec issue that may or may not be related: a show that was autorec scheduled to run at a specific time. But the network repeats this broadcast at a much later time the same evening. Now, if I reboot my tvh backend beforehand (like at 10:00 AM), it would also record this repeat, later the same evening. If I don't reboot, this would not happen. Very strange...

Anyhow, the autorec for the daily news show that I made using the webif and recently resulted in duplicate recordings looks like this:

{
"enabled": true,
"title": "RTL Nieuws",
"fulltext": false,
"channel": "03d8382c52d178be7cd6ab813e393c7b",

"start_extra": 0,
"stop_extra": 0,
"weekdays": [

"minduration": 0,

"brand": "",
"season": "",
"serieslink": "",
"creator": "192.168.1.5",
"comment": "Created from EPG query"
}

The autorec entry created using Kody Krypton and resulting in triple recordings looks like this:

{
"enabled": true,
"name": "RTL Nieuws",
"title": "RTL Nieuws",
"fulltext": false,
"channel": "03d8382c52d178be7cd6ab813e393c7b",

}

Should I do something to help you debug this, please say what I have to do.
I'll be very happy to do anything within my capabilities to help.
I guess the first move I should make is recompiling tvh with debug symbols, right?

Cheers,
Tycho
