This happened to me in SUM.

Further investigation in the logs showed an error "SYSTEM MANAGER: duplicate entry". The problem was indeed there are 2 registered instances with the same number 00. You can see that with command:

sapcontrol -nr 00 -function GetSystemInstanceList

/replace 00 with any working instance/

The problem is due to kernel/hostagent updates without restarting. The result was several old hanging sapstartsrv processes (ps -ef |grep sapstart). I could not restart the server, so I decided to kill them with the kill command.

Somehow I managed to kill more than needed, and there wasn't even one 00 instances reported by the above command, but I started it again

sapcontrol -nr <instance number> -function <StartService> <SID>

P.S. stopping starting these usually does not affect users work
