Hi All,
We may need to tune ThreadStackSize [1], before we run Java applications on
K8s. Default Linux JVM thread stack size is 1MB [1].

Hi,
Yes, this is already there in the wso2server.sh. For Kubernetes and other
container management systems, we need to set these values as limits to
avoid getting issues in runtime.

Hi Lakmal,
All of the container related images will use the default startup script

Hi All,
If we do not set MaxHeapSize in JVM which runs inside docker it will set it
as 1/4 of the physical memory. But issue is, inside the docker it will read
as total physical memory of the HOST machine rather taking allocated memory
to that docker container. So if we do not properly set MaxHeap
