Can't stop nor kill any of my containers under 0.7.0
Correction, any of my PHP ones:
PHP7 docker.io/arm64v8/php:7.4-fpm linux arm64 running 192.168.64.12 4 1024 MB PHP docker.io/arm64v8/php:8.3-fpm linux arm64 running 192.168.64.11 4 1024 MB

Command is like:
container run --name PHP -d -v /Users/someUser/Documents/Container/PHP:/usr/local/etc/php -v /Users/someUser/Sites:/usr/share/nginx/html -e TZ=Europe/Paris arm64v8/php:8.3-fpm bash -c "apt-get update && apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libpng-dev libicu-dev && docker-php-ext-configure gd --with-freetype --with-jpeg && docker-php-ext-install gd mysqli intl exif && php-fpm"

@Tazintosh When you say can't stop, does it hang or you mean you get this same error?

[dcantah]

This should fix @tuxtof's issue at least apple/containerization#439

It hang. No errror.
In fact, I’ve noticed this issue in 0.6.0 too when PHP is crashing(?) for some reason.
Even the container kill command won’t work and the only way is to kill using Activity Monitor for instance, which is not easy since all containers have the exact same process name.
