@qu1que this error implies u are running MagicMirror in a docker container,

MagicMirrorOS
or one of the docker implementations

@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?

[MMRIZE]

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.

@MMRIZE

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"],
