"Out of memory" issues - where do I begin?

Welp…

No change. System still crashes on the Pi using Chromium.

In looking at the most recent core file, it’s still showing that electron is what’s faulting.

There are no running processes of chromium and electron is still being started. Something is amiss with the configuration to where your run-start.sh script is either not being called or is not launching the correct browser for some reason.

I’ve made no changes to run-start.sh, I’ve edited package.json so that this line is gone:

"start": "DISPLAY=\"${DISPLAY:=:0}\" ./node_modules/.bin/electron js/electron.js",

And has been replaced with this one:

"start": "./run-start.sh",

config/config.js has the following setting:

var config = {
	address: "0.0.0.0", 	// Address to listen on, can be:
							// - "localhost", "127.0.0.1", "::1" to listen on loopback interfac
e
							// - another specific IPv4/6 to listen on a specific interface
							// - "0.0.0.0", "::" to listen on any interface
							// Default, when address config is left out or empty, is "localhost
"
	port: 8080,
	basePath: "/", 	// The URL path where MagicMirror is hosted. If you are using a Reverse proxy
					// you must set the sub path here. basePath must end with a /
	ipWhitelist: ["127.0.0.1", "192.168.192.0/24", "::1"], 	// Set [] to allow all IP addresses
															// 
or add a specific IPv4 of 192.168.1.5 :
															// 
["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
															// 
or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
															// 
["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.3.0/28"],

	useHttps: false, 		// Support HTTPS or not, default "false" will use HTTP
	httpsPrivateKey: "", 	// HTTPS private key path, only require when useHttps is true
	httpsCertificate: "", 	// HTTPS Certificate path, only require when useHttps is true

	language: "en",
	logLevel: ["INFO", "LOG", "WARN", "ERROR"],
	timeFormat: 24,
	units: "metric",
	// serverOnly:  true/false/"local" ,
	serverOnly:"local",

One tweak to the run-start.sh script seems to have fixed it. I changed this line:

serveronly=$(grep -v '^[[:blank:]]*//'  config/config.js | grep -i serveronly: | awk '{print tolower($2)}' | tr -d ,\"\'\\r)

To this:

serveronly=$(grep -v '^[[:blank:]]*//'  config/config.js | grep -i serveronly: | awk '{print tolower($1)}' | tr -d ,\"\'\\r)

The awk command seems to have been looking for a variable that wasn’t being passed and by changing the variable number that it was looking for, it no longer starts electron and now starts chromium.

@ember1205 hm… do this

cd ~/MagicMirror
./run-start.sh

you should see something like this

 ./run-start.sh

Ready to go! Please point your browser to: http://0.0.0.0:8090
Starting chromium browser now, have patience, it takes a minute

that last line is the key to running in split mode, server with chromium over the top…

to run it multiple times, you will have to kill the server process

 ps -ef | grep server

sam 3267 3266 1 13:13 pts/0 00:00:01 node serveronly

kill -9 3267

thx for the hint, the space after the serverOnly:

@ember1205 I just updated the script to handle with/without the space…

ember1205

Cool. I download the latest one and try it out.

Glad I can help you keep improving your code! lol

@ember1205 said in "Out of memory" issues - where do I begin?:

me too… thought I had handled that… guess not

Based on the directions you gave in this thread, the run-start.sh script won’t work. I didn’t take the time to look through the github content to see if this is covered there, but you have to do

chmod +x run-start.sh

Or the script won’t actually execute. Based on old habits, I was executing the chmod statement without even thinking about it. But, after downloading the newest script, I purposefully left it untouched and it wouldn’t run.

@ember1205 hm, thought it was uploaded with exec. will check this evening. have doctor appt shortly

thanks for the info

ember1205

I simply opened the github page, copied the link, and used wget to download it to the mirror. So, it’s entirely possible that the way I downloaded it was partly to blame. Figured I would mention it because I’m likely not the only one that might run into this, and at a minimum it could become a troubleshooting step if others run into issues.

sdetweil

@ember1205 thx. wget & curl won’t copy the execute permissions. when I install this on a pi 0 I chmod it to executable
