On applying this patch on the OES 2018 server, the Cloud Integrated Storage (CIS) agents (cis-agent.service, cis-recall-agent.service, and cis-scanner.service) are no longer supported and hence are stopped. These agents were installed as part of the NSS pattern.
These agents are stopped because with the release of OES 2018 SP1, CIS can be installed in a production environment and having the stale CIS (OES 2018) agents can impact the functionality of the OES server.
