>PS Do you know of DumpRep.exe?

If http://www.liutilities.com/products/wintaskspro/processlibrary/dumprep/ is correct

dumprep - dumprep.exe - Process Information
Process File: dumprep or dumprep.exe
Process Name: Dump Reporting Tool


Description:
dumprep.exe forms a part of Microsoft Windows XP (and later versions), in-built fault logging software. Upon serious errors this program will write the details to a text file and request the information be sent to Microsoft. This program is a non-essential system process, and is installed for third party use.


It sounds like it's in the process of writing the file, before it's gotten to the point of asking you to send it. When you crash are you way over your physical memory and therefore chewing lotso cycles swapping to disk?
