A servicing daemon is described herein for providing servicing of a running computer system (such as a filer). The servicing daemon resides and executes on the operating system of the filer and communicates across a network with a debugger that resides and executes on a remote administering computer. A debugging session is performed that complies with a protocol relating to the remote accessing of files. The debugging session provides live servicing of an application executing on the filer without requiring an actual corefile (having copied filer memory data) to be created. Rather, the servicing daemon creates a simulated corefile header that is sent to the debugger, receives requests from the debugger, and maps addresses specified in the requests to filer memory addresses. The servicing daemon then reads and retrieves data directly from filer memory at the determined filer memory addresses and sends the data to the debugger for analysis.
