Although the Linux operating system is much more stable than the Windows operating system. However, this stability is relative. That is to say, the Linux operating system may also get angry. In some cases, the system's resource usage (including CPU or memory) may reach more than 90%. To this end, the system administrator still needs to monitor the usage of system
