How to increase Jave Heap Space 24R1

Hello Everyone,

 

We attempted to print multiple reports simultaneously, but only one report was successfully printed.

Upon investigating the issue, we reviewed the Kubernetes pod logs and found Java errors in the ifsapp-reporting pod. The logs indicated the following error:

java.lang.OutOfMemoryError: Java heap space
 

When I describe the reporting pod, the java heap memory allocation was as below;

IFS_JAVA_OPTS:                -XX:MaxRAMPercentage=30
                                    -XX:MaxMetaspaceSize=594M

 

Is there any possibility that we can increase the java heap space value from the deployment or any workaround to get rid of these errors?

 

Thanks in Advance!

 

Best Regards,

Rayan

i quickly reverse engineered your numbers… seems you have set global.scale to 50 or 60 in your ifscloud_values.yaml?
set it to 100 to get a bit more memory in all your pods.

Hi ​@hhanse,

 

Thank you for the quick tip.

Since this environment is a TEST environment, we do not have enough resources to run the application with scale 100.

But I believe we can add one more ifsapp-reporting pod and try.

 

Best Regards,
