Raspberry Pi Memory Loss
-
@evroom yeah it just died, MagicMirror crashed showing the black screen, when MacicMirror was restarted boom 80% free memory. So now I’ve got watchdog on for hopefully when it crashes it will restart with 80% memory
-
Have you tried running top or (htop if installed) from a terminal cli to see which process(es) are using up the memory?
-
Could you send the output of the following commands, when running more or less normal?
free swapon -s vmstat 5 10 top -b -o +%MEM | head -n 22And the suggested htop command is also nice to look at.
Might need to be installed separately. -
@evroom restarted the hole thing so memory is good. i have no idea what this other thing is that you and @jsteel715 are talking about lol but here is what you asked for with the code. this is normal operation apart from chromium that is shutdown everytime im not using it

Could you repeat this when memory usage has increased substantially?
The chromium processes are taking up quite some memory.
I myself have none running.Did you get the latest packages?
$ sudo apt-get update $ sudo apt-get dist-upgrade -
@evroom said in Raspberry Pi Memory Loss:
$ sudo apt-get update
$ sudo apt-get dist-upgradeok so ive done the apt-get update before so not much but dam the apt-get dist-upgrade took about 10mins or so. I just turned off the chromium run in the background even when it is closed and the use accelerated hardware.

@evroom this is how the mirror runs normally no other processes than this.

So it is an electron process, hence MM process, alright.
Now find a way how to determine which module is causing this.
Which modules do you have active? -
Can you do following ?
Please do not post output that is very long.
Just want to get a feeling if these commands lead to anything, hence the MMM module eating memory$ top -b -o +%MEM | head -n 8 $ strace -T -o /tmp/strace.out -p PID_from_top_command After about 15 seconds, use control-c to stop strace. For example: $ strace -T -o /tmp/strace.out -p 904 $ grep 'name_of_MMM_module' /tmp/strace.out For example: $ grep 'mmm-systemtemperature' /tmp/strace.out $ grep 'name_of_MMM_module' /tmp/strace.out | wc -l For example: $ grep 'mmm-systemtemperature' /tmp/strace.out | wc -l
