Claim:
1. A computer system for enhanced restart of a core dumping application, the computer system comprising: a computer readable memory; a processing unit communicatively coupled to the computer readable memory; a computer readable storage medium; and program instructions stored on the computer readable storage medium for execution by the processing unit via the computer readable memory, the program instructions comprising: program instructions to stop a plurality of threads in an address space; program instructions to continue a thread, wherein the continued thread performs a core dump; program instructions to remap a computational segment to a client segment, wherein the remapping comprises: program instructions to obtain the client segment, wherein the client segment includes a plurality of client pages, and wherein the client pages comprise cached file data; program instructions to copy a plurality of segment descriptors associated with a plurality of computational pages from the computational segment to the client segment; program instructions to decrement a first count, wherein the first count corresponds to a number of computational pages identified by the plurality of segment descriptors copied from the computational segment; and program instructions to increment a second count, wherein the second count corresponds to the number of computational pages identified by the plurality of segment descriptors copied to the client segment; program instructions to close each open file descriptor in the address space; program instructions to terminate the core dumping application; and program instructions to flush the client segment to an external storage.
