Queued jobs are processed by schedule:run cron task. This task runs queue:work daemon which processed queued jobs. You can view jobs status under Manage » System » Jobs (normally there should be zero jobs in the queue).

1) Run php artisan freescout:check-requirements command and make sure that pctl extension is installed in your console PHP (without this extension FreeScout can't kill processes that get stuck).

When running the command make sure to use the same PHP as in your cron jobs. For example if in your cron you are using /usr/local/bin/php-8.0 run the command as: /usr/local/bin/php-8.0 artisan freescout:check-requirements

2) Run ps aux | grep queue command to check if queue:work daemon is running:

ps aux | grep queue
freescout  5534  0.0  0.0   9540  2292 ?        S    02:01   0:00 sh -c php 'artisan' queue:work --queue='emails' --tries=7 --sleep=3
freescout  5535  0.0  0.1 284580 34116 ?        S    02:01   0:00 php artisan queue:work --queue=emails --tries=7 --sleep=3

If there are more than 2 processes running, clear application cache (see #3) or kill them manually:

kill -KILL 5534 5535

3) If queue:work daemon is not running , make sure that you have schedule:run cron task configured.

4) Clear application cache to restart all queue:work daemons:

php artisan freescout clear-cache

5) Check daemon log: /storage/logs/queue-jobs.log
