Well, my v3 setup is only running for one month. But in fact the total uptime was approx 7 days as all this time i was fighting with an independent issue Raspberry pi 4 hard freeze, possibly overheating - #5 by chris4789 , due to which my actual uptime didn’t exceed 4 days. So, it took me a 7 days to get the problem. Isn’t it too fast for a rare problem ?
Well, perhaps you can blame me for being stupid and forgetting to lower log size limits after installing v3. In fact i had this done on my old v2.5 installation. I’ve accepted that.
Sorry, wrong, see the reply. I didn’t respond immediately because i went to test this suggestion.
