Channel locked (recording)!

Hello.
I have a VDR 2.4.0 server which is streaming to 6 clients in my house via VNSI and streamdev (for the VDR standalone clients).
My kodi machines are accessing LiveTV via VNSI server.
Once in every 2-3 hours I have a weird message in Kodi interface with the message "Channel locked (recording)!"
I have no active timers programmed.

This evening I have investigated the log and found the following:

Quote:Mar 30 00:15:15 YaVDR-VM vdr: [628] suspendoutput: output suspended by inactivity timer
Mar 30 00:15:15 YaVDR-VM vdr: [628] ERROR: Channel locked (recording)!
Mar 30 00:15:15 YaVDR-VM vdr: [628] ERROR: no OSD provider available - using dummy OSD!
Mar 30 00:15:15 YaVDR-VM vdr: [628] suspendoutput: output resumed by user action
Mar 30 00:15:15 YaVDR-VM prevent-umount-on-pause[591]: ERROR:dbus.connection:Exception in handler for D-Bus signal:

How can I get rid of this message and what is causing it?
Thank you.

p.s. In case full syslog is needed I will upload it.
