8: Zombies
Zombies are indicative of more serious issues.
Argent can delete Zombies for you but you need to get to the root cause.
First some background.
Captivating as its name is, a Zombie process is one that has terminated, but its entry is still in the process table, taking up a process ID number.
More Zombies = More Wasted Process IDs
Under a heavily loaded Linux server, a system can eventually run out of unallocated process ID numbers.
Use the Argent Rule SCP_ LINUX_MAX_ZOMBIE_PROCS to test for Zombies.
