Tvheadend

I'm getting frequent Tvheadend crashes when accessing minisatip sources.

Symptoms

I had these problems occasionally with a Raspberry Pi DVB-T minisatip 1.0 commit 0a1910b59f1d server. Now I have added an additional Digibit R1 DVB-S server with minisatip 0.8 and crashes are much more frequent.

"Frequent" means at least once per day at 02:00 (probably when the OTA EPG grabber starts) and occasionally when switching channels while watching. I can watch a full movie without problems as long as Tvheadend does not use other streams (for recording, for example), which sometimes triggers a crash. It seems that Tvheadend crashes especially when accessing two streams at the same time.

See some crash logs here: https://pastebin.com/raw/XfVU6cXj

Setup

TVheadend command line arguments: /usr/bin/tvheadend -C -c /config --satip_xml http://10.0.1.18:9090/desc.xml --satip_xml http://10.0.1.25:8080/desc.xml --trace satip,service,subscription -d -S

I'm using linuxserver/tvheadend stable-4.2.1 docker image on a Synology NAS that's got 8 GB of RAM (IP 10.0.1.19).

Minisatip command lines:

• DVB-T on Raspberry Pi (IP 10.0.1.18): minisatip -f --http-port 9090 -D 102
• DVB-S on Digibit R1 (IP 10.0.1.25): minisatip8 -f -g -D 103

I configured TCP mode for both sat-ip servers.

Additional details

Please note that I've configured unique "Device IDs" for the sat-ip servers but Tvheadend does not show them for neither servers:

Please, let me know what I can do to investigate further... Thanks!
