send-campaigns command causing resource exhaustion and DB crash

[CFS DEVS]

Hello,

I'm facing a critical issue with the `send-campaigns` command. When I run it (either via cron or manually), it spawns endless PHP processes and hits system resource limits (ulimit -u 80).

This causes the server to crash, and MySQL fails with `SQLSTATE[HY000]: General error: 2006 MySQL server has gone away`.

Even with 12 CPUs and 16GB RAM, the system gets overwhelmed.

What is the proper way to safely limit MailWizz batch processing concurrency or fork behavior? Is there a way to restrict how many processes are spawned?

PHP 8.2.28

It has never happened before, but it started happening today
