Once the initial space has been used, the VM allocates further operating system memory space in stages up to a maximum amount.

Instances with enqueue and with ABAP dispatcher 3. Stateful requests are a particular challenge for the load balancer, since the HTTP protocol only supports stateless requests. The corresponding Java cluster elements are started using the Startup and Control Framework.
