Enough Processes

Create the following file as /etc/sysctl.d/01-pidmax.conf, then reboot your system.

kernel.pid_max = 132

What it does

It limits the system to a maximum of 132 processes, which is typically not enough to complete a normal boot.

Why it works

This sets the highest process ID that the kernel can assign to a process to 132, effectively limiting the system to 132 processes in total.
