Server Forker Problem

[tintifaxxx]

Hi,

i always run into an error, when trying to use the new Contao Manager (1.3.3) The previous Contao Manager Version was working fine.

Contao 4.95 - First error, when updating to 4.9.9

Can you please tell me the requirements for the server to get the forkers working. Provider says system requirements are given

Here is one of the error messages:

Thank You

[aschempp]

That's very interesting, because the "forker" concept has not changed since the early days. Do you know what platform your server is running on? Did you manually configure the PHP binary path or was it automatically configured?

[tintifaxxx]

PHP binary path was configured manually, told by provider /opt/plesk/php/7.4/bin/php platform is linux - 4.15.0-70-generic #79-Ubuntu What else do you need to know ? phpinfo is uploaded

[aschempp]

The Contao Manager uses so-called "forkers" to send a process to the background. There are multiple implementations for different platforms/server setups: https://github.com/contao/contao-manager/tree/1.3/api/Process/Forker

On Linux it usually works with both Nohup (exec nohup …) and Disown (… & disown, so I'm not sure whats special on your server 😞

[aschempp]

In the next version, we will fall back to inline processes if background forking does not work (see b897f26f27faa13169413217bed266df90b02e7e).

Cleared cache of the contao-manager and still doesn't work.

Happening on multiple websites on PHP 8.1 and 8.2 (Can't test on PHP 8.3 because standard image libraries don't work on the whole server if having one Project on 8.3 🙃 )

Works after a service restart
