pstop - Man Page

pstop PID...

Stop each process by sending SIGSTOP.

PID

Process ID. A /proc/pid path may also be used, allowing shell expansions like /proc/* to target all processes on the system.

0 on success, non-zero if an error occurs (such as no such process, permission denied, or invalid option).

/proc/pid/*

Process information and control files.

A process can do nothing while it is stopped. Stopping a heavily used process in a production environment, even for a short amount of time, can cause severe bottlenecks and even hangs of dependent processes, causing them to be unavailable to users. Because of this, stopping a process in a production environment should be avoided.
