Sathish, I was not able to find recommended memory requirements in cas docs. This guide has a suggestion https://paulchauvet.github.io/deploying-cas/setting-up-the-environment/tomcat/systemd-service/
Memory is cheap, I would start at 2G. See tomcat docs to configure this. Cas also has some performance testing options https://apereo.github.io/cas/6.6.x/high_availability/High-Availability-Performance-Testing.html Ray On Tue, 2023-10-31 at 03:10 -0700, Sathish Sekar wrote: Notice: This message was sent from outside the University of Victoria email system.

But when I upgraded to 6.6.9 it is showing heap java.lang.OutOfMemoryError: Java heap space when i deployed in clustered servers.
