Please assign this to me. @zhoujinsong
I think it's necessary to allocate space for the JVM's non-heap memory so we need to set the JVM's heap memory smaller, right?

Thank you @Marvel-Gu. Assigned

Exactly. We should limit the size of the JVM heap memory, for example, to 80% of the pod's memory limit.
