Description
When the ESXi Shell or Secure Shell (SSH) services are enabled on a host, they will run indefinitely. To avoid having these services left running, set the "ESXiShellTimeOut". The "ESXiShellTimeOut" defines a window of time after which the ESXi Shell and SSH services will be stopped automatically.
