the number of active processes that are checked every 5 seconds, and then the values calculated by a specific algorithm. If this number is divided by the number of logical CPUs, the result is higher than 5, indicating that the system is overloaded. Second line: tasks-task (process), the system is now a total of 183 processes, of which 1 are running, 182 in hibernation (sleep), stoped state of 0, zombie State (zombie) has 0. Third line: CPU state 6.

files It is important to note that if you can use the "-" number indefinitely, And the priority for user throttling is higher than for groups. In fact, in a Linux server, it is acceptable for a user process to run for a long time.
