Well I wasn't insisting that Watchdog was causing it. I was simply stating what happened and why I thought it did.
Yes. I renamed the watchdog, started the player (watchdog does not start with the player) and that is what was shown. I have left it like that for about 23 hours and it says the exact same thing. Nothing else is being logged. There is only one instance of each player per machine. There are no other processes related to Xibo on any machine, apart from the one player.
My CMS version is 1.8.2 (docker installation) and the players are 1.8.3. I will update the CMS, as I hadn't realized there was an update. (I had reinstalled the players trying to select install for only one user before and didn't realize the version had been updated.)
In the CMS, I have the XMR Public Address set under Settings, in the Display tab, and no where else. I have gone into the settings for each player and checked reconfigure XMR.
I'm going to update the CMS after this post, and if that fixes the issue, I will post and let you know.
