1. A system for servicing an application executing on a local computer using an administering program executing on a remote computer connected with the local computer through a network, the system comprising:

  • the local computer comprising a local memory storing data;

    a memory virtualization component configured to produce a corefile comprising a corefile header representing the local memory of the local computer, wherein the corefile does not comprise data copied from the local memory; and

    a remote procedure call (RPC) component and a reverse-address mapping component configured to implement the servicing of the application using the corefile, wherein;

    the RPC component is further configured to receive a read request from the administering program, the request comprising a dummy address having a particular value, and to send the corefile header to the administering program in response to the read request; and

    the reverse-address mapping component is further configured to determine that the read request is a request for the corefile header by comparing the particular value to a predetermined value associated with the corefile header.
