We have two domino 8.5.1 servers running with cluster configuration. One act as primary and another is for secondary. After we implemented DAOS in secondary domino server, we found that nserver.exe utilized high CPU in domino server (Primary domino server) at the same time every day. It caused slowness to the primary server and unable to provide notes services to clients.

Please, could you advise why nserver.exe cause high CPU utilization at domino server? Is there any solution to fix this issue, please, advise?

Thank you
