what caused this error? When did it happen (what where you executing)? Do you have a stacktrace in your error log? (storage/logs/laravel.log)
Do you have an infinite loop that never ends and eats up memory?

Out of memory error on server
Hello, On my remote server(ubuntu 16, PHP 7.2.7-1+ubuntu16.04.1+deb.sury.org+1 ) in laravel 5.5 project I got error:

I restarted apache server times.
What is wrong and how to fix the error?
Thanks!

So, trying to find a match for all the dependencies is taking more then the ~570MB you have allowed for php (or your server hosting).
Check the memory usage on the server with
free -m

That is Ubuntu hosting(I created it a pair of weeks ago) under Digital Ocean:
root@ubuntu-boxBooking-Dev:/var/www/html/box-booking# lsb_release -d; uname -r; uname -i

I had laravel 5.5 app installed. I pulled changes from git and had to install intervention/image :
# composer require intervention/image

Also I tried:
# composer update

- Removing doctrine/dbal (v2.6.3)
The following exception is caused by a lack of memory and not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details
I see
not having swap configured
error description above and 0 value in free command above. Is it issue and how to fix it?
Also installing Ubuntu hosting under Digital Ocean I did not notice any swap options...
Aslo can be rebooting of the system salve the problem? Usually I reboot the ubuntu(I use kubuntu 18 on my laptop) running under root:
reboot
Is it what I have to run in my case or other command preferable?

As you can see:

You have to little RAM in this server (only 1 GB total), but composer usually needs around 1GB to be able to resolve all dependencies. You only have around 560MB free.
There are 3 things you can do:
- Setup your dev environment to match your server as close as possible (so vagrant + ubuntu + same php version + more memory) and do
"composer update"locally, and"composer install"on the server, this way the server doesnt have to do the resolving, it just installs what your dev environment concluded to be the needed packages. - Increase your server's RAM by upgrading to a higher package
- Add swap to your server so it can handle the overload of memory by using it's harddisk in those situations.
For #3 you can follow this tutorial to setup a 1GB swap space on your server:
