3284851 - Message Server and Enqueue Server in yellow state after deactivating the parameter system/secure_communication


Both the Message Server and Enqueue Server remain in YELLOW state with "Running but not responding" after the parameter "system/secure_communication" was deactivated (set to OFF).

This can be seen at the end of the "sapstartsrv.log" file or with the command "sapcontrol -nr XX -function GetProcessList".

For example:

msg_server, MessageServer, YELLOW, Running but not responding, [date and time], [uptime], [PID]
enserver, EnqueueServer, YELLOW, Running but not responding, [date and time], [uptime], [PID]

Despite this, the system works normally.

Note: during an installation, system copy or upgrade, the procedure does not move forward because the ASCS processes never reach the GREEN state.
