ENOMEM errors coming from UpdateNotification and MMM-PIR-Sensor modules

My mirror has crashed twice in the past 24 hours due to ENOMEM errors, the stack trace from the error log is as follows:

I’ve had the mirror running for about a week, this is the first time I’m coming across this. Does anyone know what I can do to resolve this?

ENOMEM errors

What modules are you running? It’s an out of memory error…

malicious_banjo

@cowboysdude Oh, my bad. Those two are both the modules that failed both times, assumed they were the root cause.
Modules:

UpdateNotification
default Clock
default Calendar
default Compliments
default CurrentWeather
default Weatherforecast
default NewsFeed
MMM-Scrobbler
MMM-My-Commute
MMM-pihole-stats
phone notifications

cowboysdude

Comment out all of these:

MMM-Scrobbler
MMM-My-Commute
MMM-pihole-stats
phone notifications

like this:

          {
            disabled: true,
            module: 'MMM-NPMWeather',
            position: 'bottom_bar',	
		config: {
				location: "76123",
				read: "F",
				maxWidth: "50%"
			}
            },

just add disabled: true, to the top of each one like the example then try rerunning the mirror…
If it runs okay then one at a time change the true to false… and rerun…

That’s troubleshooting to see if any of the modules are causing this issue.

@cowboysdude I’m expecting the error to come from the pihole module, it didn’t start happening until I added that yesterday.
If/when I diagnose that it’s the source, how would you recommend I fix it?

pihole module

I would suggest uninstalling the pihole module… pihole uninstall [I believe I read somewhere]
