hen I run my application on the microSd ( having 4G ) on my Beaglebone, I get this error :

The build failed because the process exited too early. This probably means the system ran out of memory or someone called kill -9 on the process.

It is the problem of size of my microSD ?

How can I fix that please ?

That's kinda rude..

So you ran out of RAM and the OOM killer stopped it.. Add some swap.

sudo fallocate -l 512M /swap.file
sudo chmod 600 /swap.file
sudo mkswap /swap.file
sudo swapon /swap.file

Did you open that file ^

It is the problem of size of my microSD ?

Or the location of the moon..

Thank you Robert.
But when I used a microSD with 16G, I need to make a swapfile also?

  IF it is running out of RAM then yes, you likely need a swapfile.
Programs don't run "on the SD card" (or eMMC). They are /stored/ as files
there and get loaded into RAM when executed.

  The BBB RAM is only 512kB. If the program needs more RAM than is
available the OS will kill it. Using a swapfile lets the OS copy currently
idle code/data from RAM to the SD card (or other device -- I'd recommend
using a USB hard-disk, to reduce wear on flash memory) and map in the freed
RAM as more data space for the current program.

"""
Flash memory has a finite number of erase-write cycles (see Limitations of
flash memory), and the smallest amount of data that can be erased at once
might be very large (128 KiB for an Intel X25-M SSD [27]), seldom
coinciding with pagesize. Therefore, flash memory may wear out quickly if
used as swap space under tight memory conditions. On the attractive side,
flash memory is practically delayless compared to hard disks, and not
volatile as RAM chips. Schemes like ReadyBoost and Intel Turbo Memory are
made to exploit these characteristics.

I create a swapfile and I run it, but every time, I get the same error…

Such as I run my application on the microSD having 16G on my BeagleBONE.

  Where did you create the swap, and how big is it? Best would be to show
the actual commands used.

This is how I created my swap file :

[image: swaap.png]

  And once again you attach an 80MB IMAGE that is unusable for cut&paste
into a command line. I don't write code in a paint program. In the future,
I will ignore any message with an image of a screen capture where text
cut&paste would be useful.

  In a second console window, run

top -o '%MEM'

and monitor the display while running whatever is using up memory. That
/should/ put the main memory hog process at the top of the list. You should
also be seeing the summary row for "KiB Swap" showing total swap usage.
(NOTE: you have to watch this live, since as soon as the OOM kill takes
place, that process will disappear from the display).

  If the total swap usage is still running out, I can only suggest trying
with a larger swap file (one reason I also recommend using a USB hard-drive
-- since each GB of swap is 15% of an 8GB SD card, and a process using a
lot of swap /could/ wear out the SD card [depends on if it is just
allocating and writing to swap vs thrashing stuff in and out of swap
space]).

  If it still gets OOM killed with 2 or 4 GB swap -- I'd think there is
something wrong with the program you are running. The only time I've had
OOM kills was when I was running the HINT benchmark (about two years ago)
and had to put in that hard drive for swap (I /did/ kill a Raspberry-Pi SD
card with that benchmark before re-running using the drive on it). HINT,
however, is smart-enough to detect when the run-time on swap grows rapidly
and ends the benchmark run at that time. On a bare-board embedded system,
HINT ends the run when malloc() returns 0 memory -- apparently Linux kills
the process rather than having malloc() fail.

  Yay! A text cut&paste instead of an image! Thank you.

When I run this command, I get :

  At the moment you did this cut&paste, "node" was sucking up 73% of the
available memory (and practically NO CPU time -- the journal and top are
the CPU users). Unless I misunderstood the documentation for "top", %mem is
based upon the total of RAM and swap. That's nearly 1.2GB right there
(though some is in memory shared with other processes)..

  Google on npm, ELIFECYCLE, and react seems to show lots of problems
with it, none with a clear explanation or solution. Some seem to imply a
problem with how packages were installed (mismatches, etc.).

  Other than kicking the swap space up to maybe 4GB as a test, I'm now
out of suggestions. I don't do stuff with node.js (I can work with Python
thread, Ada tasking -- but systems based upon asynchronous callbacks just
confuse me, and that is what node.js relies upon; even Python's async
system confuses me). Whatever node is running is sucking up memory, and one
has to be ready to debug node.js source files to make any progress.

Thank you for explanation.
In fact, Iwant to run my application developed in ReactJS and node JS at the start of Bealebone, it is necessary to execute the node then the Reactjs, the node is always executable, while reactjs once executable and another time I wait a lot and I do not does not get the application, it can generate systemd time?

  I'm sorry -- that sentence is too convoluted to be understandable.
"...and another time I wait a lot and I do not does not get the
application..." in particular.

<https://en.wikipedia.org/wiki/React_(JavaScript_library)&gt; does state:
"""
A criticism of ReactJS is that it has high memory (RAM) requirements, since
it uses the concept of a "Virtual DOM". This is where "a representation of
a UI is kept in memory and synced with the 'real' DOM by a library such as
ReactDOM."
"""

  As I'd mentioned -- I don't do node.js at all. So I can't interpret
your original traceback enough to tell if the failure occurs starting
ReactJS (if that is even an activity -- if it really is a library, it would
be your application that calls the library; not ReactJS calling your
application).

  Does ANY React-based application cause the failure, or only when your
application is invoked? If it is only your application, I'd suspect that
1) your application is much too complex and large for the intended usage
(ReactJS was meant to generate web-pages using JavaScript for interactive
user interfaces);
2) your application has something that is maybe recursive, with each
recursion eating more and more memory (given that node.js relies upon
asynchronous/callbacks I could see this as a problem -- something gets
triggered which attempts to respond in such a way that it triggers itself
again...)

I mean that when I run my application on the startup, once it will be executed, in other once, it does run after 30 minutes
