In the description of the Java Virtual Machine specification, in addition to the program counter, there are several other run-time regions of the virtual machine memory that have OutOfMemoryError (called Oom) exception, and below are some examples to verify the occurrence of the exception. In the example below, some of the virtual machine parameters are set in the annotation, and after "VM Args", if you are using a console command to execute the program, put these parameters directly after the J

These technologies may be outdated and not used in the "real world", but you must remember that if you want to improve the technology, you must know the past and use its strengths for your own use! Definition of heap and itsXPWorking Principle A heap is a place where processes store data. Each process can dynamically

Statement: The main content is from The Shellcoder's Handbook, which extracts Important Notes and adds some personal understanding. If there is something wrong, be sure to point it out. Almost all malloc implementations use metadata to store the location, size, or special data related to small blocks. Dlmalloc stores the data in buckets, and some malloc stores the data in a balance tree structure. These metadata are generally stored in two places: malloc implements the global variables used by

is not enough to create additional threads, either there are too many threads created, or the stack space is indeed small. "Resolution": Because the JVM does not provide parameters to set the total stack space size, but can set the size of a single line stacks, and the system's user space is 3G, in addition to text/data/bss/memorymapping a few paragraphs, heap and stack space is limited , it is the elimination of the other long. Therefore, there are

Java heap memory overflow As long as you constantly create objects and ensure that there is an accessible path between the GC roots and objects to avoid the garbage collection mechanism clearing these objects, The memory overflow exception occurs when the number of objects reaches the maximum heap capacity limit.
