Self Hosted V5 Email Not sending

I have recently upgraded from V4 self-hosted but I am having an issue with the sending of emails

looking at the storage/logs I see the following

[2022-10-14 05:05:04] production.ERROR: Call to undefined function Illuminate\Queue\pcntl_signal() {“exception”:"[object] (Error(code: 0): Call to undefined function Illuminate\Queue\pcntl_signal() at /usr/www/users/FTPUSER/vendor/laravel/framework/src/Illuminate/Queue/Worker.php:679)


Which operating system/web server are you using?

The info here may help:

I am using Linux/Debian managed hosting on a dedicated server

the support department has advised
“Our System Administrators advised that this extension will remain disabled on our servers as it is not suited; this extension is for executing code which is why it doesn’t work on our web servers, which we do using Apache.”

@david do you have any suggestions?

Unfortunately this is a requirement of the framework we are using.

One potential solution would be to try running the app with QUEUE_CONNECTION=sync

this may bypass this particular code path.

thank you

changing to “QUEUE_CONNECTION=sync” worked
