@ -240,15 +240,9 @@ This section allows you to configure the background process that is triggered by
The process does check the available system resources before creating a new worker for a task.
Because of this, it may happen that the maximum number of worker processes you allow will not be reached.
If your server setup does not allow you to use the `proc_open` function of PHP, please disable it in this section.
The tasks for the background process have priorities.
To guarantee that important tasks are executed even though the system has a lot of work to do, it is useful to enable the *fastlane*.
Should you not be able to run a cron job on your server, you can also activate the *frontend* worker.
If you have done so, you can call `example.com/worker` (replace example.com with your actual domain name) on a regular basis from an external service.
This will then trigger the execution of the background process.

@ -227,15 +227,9 @@ In diesem Abschnitt kann der Hintergrund-Prozess konfiguriert werden.
Bevor ein neuer *Worker* Prozess gestartet wird, überprüft das System, dass die vorhandenen Resourchen ausrechend sind,
Aus diesem Grund kann es sein, dass die maximale Zahl der Hintergrungprozesse nicht erreicht wird.
Sollte die PHP Funktion `proc_open` auf dem Server nicht verfügbar sein, kann die Verwendung durch Friendica hier unterbunden werden.
Die Aufgaben die im Hintergrund erledigt werden, haben Prioritäten zugeteilt.
Um garantieren zu können, das wichtige Prozesse schnellst möglich abgearbeitet werden können, selbst wenn das System gerade stark belastet ist, sollte die *fastlane* aktiviert sein.
Wenn es auf deinem Server nicht möglich ist, einen cron Job zu starten, kannst du den *frontend* Worker einschalten.
Nachdem dies geschehen ist, kannst du `example.com/worker` (tausche example.com mit dem echten Domainnamen aus) aufrufen werden.
Dadurch werden dann die Aufgaben aktiviert, die der cron Job sonst aktivieren würde.
