Process D Status Detection

When Global Cache is started, a detection process is automatically started to periodically check whether the Global Cache and CCM processes are in the D state. If a process is in the D state, exception information is recorded in the messages log file for you to manually handle the exception. Whether the detection process is successfully started does not affect the startup of the Global Cache process.

After the process enters the D state, the cluster management module detects that the process is faulty and migrates services on the faulty node to other nodes. Then, services are restored.

If an alarm indicating that a process is in the D state is recorded in messages, manually restart the server.

After the server is restarted, the process is automatically started. After identifying that the process is recovered, the cluster management module migrates the services back to the node and recovers the services.
