In Java, the default and maximum heap size are allocated based on this â ergonomics algorithm. Heap sizes. Initial heap size of 1/64 of physical memory up to 1Gbyte. Maximum heap size of 1/4 of physical memory up to 1Gbyte.
The Permanent Generation (PermGen) Heap is a heap in the JVM dedicated to storing the JVMâs internal representation of Java Classes (and also interned String instances).up, it happens. When something holds onto a reference to an object instance, it cannot be garbage collected, eventually if enough errant references are held, or the graph of other references onwards from the errant reference is large, the GC cannot free enough memory and the heap is exhausted.
