Hi at all, actuall we have an CPU issue on our database server (OE 10.2B08) after updating the clients to version 11.7.4. As you can see, in the following screenshot (from our monitoring system, please note the date format), the CPU consumption increased after the update: The higher consumption is caused by a stateless appserver, which runs on the database VM, allthough we haven't increased the connected users or changed the code. Aside the from the update, we haven't changed anything in the environment. The database and appserver runs on the same VM ( Windows Server 2008 R2 on an ESX-Host with 2 Sockets x 4 CPUs (Intel Xeon Gold 2646). Referenced to the following posts, a client with a higher major release can connect to a database and appservers with a lower major release: Progress KB - What are the version compatibilities for Appservers in OpenEdge 9.x,10.x,11.x? Progress KB - Progress OpenEdge Connectivity rules with previous/later versions Progress KB - What Type of Database Connection is possible from Client to Server when the Progress versions differ Why have we done this: Actuall we have a migration project to update our servers from Windows Server 2008 to Windows Server 2016. In the first step we migrate the clients (based by the fact of the compability of the different versions). After this we migrate the servers. Maybe someone has an idea, what causes the cpu consumption and what we can do to reduce it. Best regards from germany Jochen
