This process holds database content in memory after shutdown (I
believe, for 1 hour by default) to facilitate fast startup. You can
disable it. See SAP note 2159435.

Well, this is the primary service that handles all requests from
sapcontrol. It is sort of supposed to be always running. Resource
agent handles missing sapstartsrv during activation.

I guess if you have a valid use case you may try to open a service
request or github issue to also stop sapstartsrv.
