Heap Memory
Learn about memory based sessions, dead time memory wastage, undesirable low memory situations, and reclaiming reachable objects to avoid out-of-memory errors.
Memory-based session
One such hard limit is memory available, particularly in interpreted or man-aged code languages. Take a look at the following figure. Excess traffic can stress the memory system in several ways. First and foremost, every user has a session in the back-end of a web app. Assuming we use memory-based sessions (see Off-Heap Memory, Off-Host Memory), for an alternative to in-memory sessions, the session stays resident in memory for a certain length of time after the last request from that user. Every additional user means more memory.
