"Out of memory" issues - where do I begin?
-
@ember1205 trailing ; is ok either way
-
Updated and restarted the MM process. I will keep the three browsers hitting it and wait and see if it errors out again. Sometimes, this can literally take days while other times it can occur multiple times in an hour.
-
@ember1205 each browser is loading the images independantly… the server side just returns the list of images once for each
-
So, the extra “stress” isn’t actually stress on the Pi at all?
-
@ember1205 well, the file system loading of the images will be thru the pi, but nothing else…all the display side is done in the browser (which is where it ran out of memory)
-
Well, it isn’t a LOT of progress, but it’s progress.
It’s still crashing. But I managed to get a core dump. And it says that it’s Electron that’s crashing. The initial output from bt has me a little confused as I can’t tell if it didn’t load the symbol file correctly, or if the info just “unknown”. Here’s what I get from a bt command:
Core was generated by `/home/pi/MagicMirror/node_modules/electron/dist/electron --type=renderer --auto'. Program terminated with signal SIGTRAP, Trace/breakpoint trap. #0 0x02760514 in ?? () [Current thread is 1 (LWP 6298)] (gdb) bt #0 0x02760514 in ?? () #1 0x027603d8 in ?? () Backtrace stopped: previous frame identical to this frame (corrupt stack?)Not really sure if there’s anywhere to go from here. :/
-
@ember1205 but the other browsers kept going?
i don’t think the symbols are available,certainly not for modules, if that is where the problem is
I would add MMM-Logging (my version) which merges the logs from browser and node_helpers into one log -
Hmmm. Not sure about other browsers since I had shut those down. I’ll wait until it crashes again and see if a secondary browser will keep running.
-
I have confirmed that only Electron crashes on the Pi itself. The MM server does not experience any hiccups and remote browser connections remain functional.
I at least now understand WHAT is crashing. Next steps might be to figure out WHY it’s crashing and potentially remedy it.
-
@ember1205 note that we are trailing release of electron quite significantly (we are on 6.1.7 and latest is 9.x.x) … you might try moving up to a different version, no guaranty that MM will run tho… or what the other impacts are…
as i said back a few, with a minor startup change, you can get chromium to be the viewer on the pi.
