Root Cause:

    Monitor process use ntp command regularly but not close command gracefully.

    The improperly closed command has resulted in zombie processes remaining in the system. 

    Over time, these have consumed system resources, eventually causing the system to malfunction.


Solution:

    Use pclose after poepen to execute command done.
