Hi Everyone, I have been leaving my Pi running for longer periods and I'm seeing that the browser Chromium is crashing. Node Red itself is still up and running and if I point an external browser at it all is good. The only clue I have is this: [Chromium Error] the line of code inside the exec node is: DISPLAY=:0 chromium-browser --noerrdialogs --disable-infobars --kiosk http://localhost:1880/ui -start-fullscreen enable-logging --v=1 If I google the problem there is information which points to increasing the buffer size and other stuff I don't understand. If anyone could point me in right direction as to how to increase the buffer size please. I have since connected three msg nodes to the outputs of the exec node and am waiting........ Cheers. Paul.

Hi @Colin & @Andrei I believe I have solved the problem by using the switch --log-level It sets the minimum log level. Valid values are from 0 to 3: INFO = 0, WARNING = 1, LOG_ERROR = 2, LOG_FATAL = 3 So I used it like this --log-level=3 and all error messages have stopped! So the cmd line is now DISPLAY=:0 chromium-browser --noerrdialogs --disable-infobars --kiosk --start-fullscreen --log-level=3 http://localhost:1880/ui :man_dancing: I'm in Norwich, Norfolk, UK. Thank you both for your help. Cheers. Paul.

Hi @Colin, When I change this I get a red circle and an error code -2 Cheers. Paul.

What is the text of the error. Show Full Message in the three debug nodes and expand the contents.

Hi @Colin, Here it is. [image] [image] The only message is in the return code. Cheers. Paul.

Odd, could you export that flow and paste it here please. [Edit] Is there no message at all on output 1 or 2?

No other messages. Sorry I can't remember how to format the code.

Yes, you are right, I wonder about the error. I will try a few things. It seems likely that the fact that you are making it buffer the output is responsible for the buffer overflow.

@Colin, Thank you Just to show I can do it!! :upside_down_face: :wink: [{"id":"3665f925.450a76","type":"exec","z":"e5593c90.29dda","command":"DISPLAY=:0 chromium-browser --noerrdialogs --disable-infobars --kiosk http://localhost:1880/ui -start-fullscreen enable-logging --v=1","addpay":false,"append":"","useSpawn":"true","timer":"","oldrc":false,"name":"Kiosk Display","x":370,"y":70,"wires":[["c3c8d968.9e3898"],["9bc4ab56.ff2458"],["ae8236a8.de0d08"]]},{"id":"4ba01b75.94a9e4","type":"inject","z":"e5593c90.29dda","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":true,"onceDelay":"1","topic":"","payload":"","payloadType":"date","x":180,"y":70,"wires":[["3665f925.450a76"]]},{"id":"c3c8d968.9e3898","type":"debug","z":"e5593c90.29dda","name":"stdout","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":590,"y":40,"wires":[]},{"id":"9bc4ab56.ff2458","type":"debug","z":"e5593c90.29dda","name":"stderr","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":690,"y":70,"wires":[]},{"id":"ae8236a8.de0d08","type":"debug","z":"e5593c90.29dda","name":"ReturnCode","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":630,"y":130,"wires":[]}]

Try this as the command bash -c "DISPLAY=:0 chromium-browser --noerrdialogs --disable-infobars --kiosk http://localhost:1880/ui -start-fullscreen enable-logging --v=1"

[image] Colin: bash -c "DISPLAY=:0 chromium-browser --noerrdialogs --disable-infobars --kiosk http://localhost:1880/ui -start-fullscreen enable-logging --v=1" Hi @Colin, Using that in spawn mode seems to work getting this repeatedly out of stderr. Is it actually an error? it may be this message which is filling the buffer. [image] I'll reboot everything and let it run. Thanks for your help. Cheers. Paul.
