Instance memory limit

[former_member335051]

Hello colleagues, we are working on BTP with several applications. We have maintained an instance memory limit per instance (2.8GB). Our autoscaler is doing up/downscaling only dependent on the CPU load. Now, 2 instances are running , CPU load per instance is quite small (about 10%) but memory consumption is increasing. The question is what is happening if the memory limit per instance (2.8 GB in our case) is reached or even exceeded ?
Will processes be crashing or will memory from other instances are taken or what else is happening? What is the meaning of the instance memory limit in detail at all ?
