I have the same issue, wondering if it might have something to do with Docker and support for Apple silicon as I am running on a 14" Macbook Pro with M1 Pro chip.

You can also run docker compose up httpd php mysql -d to run it in the background if the warning bothers you.

Either way would be nice to hear what the fix is as I am also not sure

Also an issue for me on a new Appe silicon M1 MacBook. The same files and config don't report this warning on a 2014 rMBP

Yes, I'm also running on a Macbook Air with M1 chip

I having this issue on MacBook M1 Pro too.

I'm also having the same issue, and also running a M1 Macbook Pro.

@onasipim this is just a warning and should not affect anything. Simply ignore it as I have not seen any functionality that was broken by this. I'm going to close this issue. If you encounter anything which is not working due to this warning, please clarify.

@cytopia Can we please reopen this issue? I can submit PR but don't know where. I think the fix is pretty easy.

While running on M1 Macbook Pro, pidof in container(s) does not return anything for any running process if the image is not ARM64, because every program is being run by qemu-x86_64.

When I bash into my running php7.4 container I see running rsyslogd and eg. php-fpm but like this:

root      4148  0.1  1.1 692572 93892 ?        Sl   20:36   0:00 /usr/bin/qemu-x86_64 /usr/local/sbin/php-fpm
root      4146  0.1  0.2 298752 16436 ?        Sl   20:36   0:00 /usr/bin/qemu-x86_64 /usr/sbin/rsyslogd -n

The pidof does not return anything for eg rsyslogd because qemu-x86_64 is the process being run (with rsyslogd as parametar)

root@php-7.4.27 in /shared/httpd $ pidof rsyslogd
root@php-7.4.27 in /shared/httpd $ pidof php-fpm
root@php-7.4.27 in /shared/httpd $ pidof qemu-x86_64
12756 12754 10440 7419 7416 7415 7413 7127 4168 4164 4162 4158 4156 4154 4150 4148 4146 1

But actually pgrep - does:

root@php-7.4.27 in /shared/httpd $ pgrep -f rsyslogd
4146
root@php-7.4.27 in /shared/httpd $ pgrep -f php-fpm
4148

The solution to stop the logs is to bash into php container and change /usr/local/sbin/postfix.sh

if ! pidof rsyslogd >/dev/null 2>&1; then

to

if ! pgrep rsyslogd >/dev/null 2>&1; then

@guycalledseven looks legit. Will re-open and prepare something for you to test out.
