[SOLVED] random black screen

@sdetweil

Thanks for the reply, but no docker installed in that raspbery, I’ve installed following the standard method 3 or 4 years ago, and doing the updates when they are ready. I’ve also have 2 backups of the entire micro SD. But maybe I’ll try a clean installation someday and see what happens.

@qu1que

sounds like a memory problem on your raspberry pi, may other applications are running beside mm which need much memory or some modules of mm are “eating” memory …

[sdetweil]

@qu1que maybe increase the swap space?

This might be not related, but why are your newsfeeds so many and frequently fetched?

[qu1que]

@MMRIZE

I don’t know, I have now 14 url of rss feeds, But I’ve tried with less of them and the error does not disappear.

[MMRIZE]

Usually broker_posix.cc(46) Received unexpected number of handles error might seem to happen when the memory is insufficient for various reasons. I suspect you try to open too many files(newsfeed??) at once.

PS
newsfeed itself might not be the reason. (14 feeds are not TOO MANY). But your other module/process would be eating memory.

Maybe, I’ll try disabling some modules. Thanks. i will tell u when I try it.

@MMRIZE

The thing is, now that I remember, during the weekend I disabled completely newsfeed module, and the error does not disappeared. Now I’ll try disabling more modules.

I’m starting to see my problem…

Fortunately I had saved an old config.js file with less modules than the one I have now. In studying the differences, I find this in my current config.js file:

Too many calls to the newsfeed module, surely that’s the reason for the error.

This is the configuration in the MMM-Pages module that was giving me problems

{
module: 'MMM-pages',
     config: {
          modules:
               [[ "calendar_monthly", "MMM-Tools", "MMM-OpenWeatherForecast", "newsfeed"],
               [ "calendar", "MMM-AirQuality"],
               [ "MMM-TelegramBot", "MMM-EyeCandy"],
               [ "calendar_monthly", "MMM-Tools", "MMM-OpenWeatherForecast", "newsfeed"],
               [ "MMM-SolarPicture", "MMM-Lunartic", "MMM-Comics"],
               [ "MMM-Comics" ],
               [ "MMM-RAIN-MAP" ],
               [ "calendar_monthly", "MMM-Tools", "MMM-OpenWeatherForecast", "newsfeed"],
               [ "MMM-RandomPhoto", "MMM-History"],
               [ "MMM-WeatherChart"],
               [ "MMM-AirQuality", "newsfeed"],
               [ "MMM-Wallpaper"]],
rotationTime: 30000,
fixed: ["alert", "updatenotification", "clock", "MMM-OpenmapWeather", "MMM-page-indicator"]
}
},

@qu1que MagicMirror can only show or hide modules. it will load all defined in config.js, and then pages will make them show or not…

sone modules, not many, will sleep when hidden and restart on show. I don’t know if newsfeed is like that
