Concurrent dumping of large address space

A computer system for managing concurrent system dumps of address spaces of memory, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices and program instructions which are stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
• program instructions to analyze address space of memory to determine high priority areas and low priority areas of the address space;
• program instructions to stop all application threads of memory;
• program instructions to perform system dump of all the high priority areas of the address space;
• and
• program instructions to initiate a background thread that performs a system dump of the low priority areas in background of the address space, and allowing all of the application threads of memory to restart.
