Linux memory overcommit
Linux memory overcommit Linux is generous in terms of memory, it will almost never fail on requests from malloc(3) with friends. What does this mean in practice and how may it be a potential issue?
In short, overcommit memory means that the system will give the application so much memory it's asking for, even if the physical memory is not available. How does this work? Well, the requested memory comes with one small restriction; the application is given as much memory it demands if it not going to use it.
