"Out of memory" issues - where do I begin?
-
@ember1205 i run that module every day all day and don’t see any problem, but… try this
edit MMM-ImagesPhotos.js
add the line shown below
img.style.top = result.targettop+"px"; // line 271 img=null /// add this line // if another image was already displayed let c = self.fg.childElementCount;
-
should it be:
img=null;
???
-
@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.
