CAS 6.6.9

[Sathish Sekar]

Hi Team,

I have upgraded CAS 6.3.7.4 to 6.6.9. After deployment I'm getting java.lang.OutOfMemoryError: Java heap space and server is getting stopped. It is stand alone application running in 3 clustered servers. Tomcat Catalina opts memory min 512 and max 512. I don't find any exceptions in logs. But my catalina.out.log is crossing more than 500mb in usage. Kindly do needful. Please find the logs below

Hello try to give more memory (set the Xmx jvm property ) 512 is very low in my opinion. 

Best regards.

Thanks Mohamed Amdouni. I'll give a try

Earlier I was using CAS 6.3.7.4 at that time we had tomcat server minimum 512 and maximum 512 memory. But when I upgraded to 6.6.9 it is showing heap  java.lang.OutOfMemoryError: Java heap space when i deployed in clustered servers. Can you provide more suggestions

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
