I have an application I wrote to take a xen core dump and build a windows crash dump from it, and with the same input file, on one server it runs to completion and on the other it reports errors to the read and write functions...
I have md5sum'd the exe and the input file, and both are identical on each server.
Actually it turns out they aren't equal - the original file is sparse but loses its sparseness when copied to the other server. Strange though... shouldn't sparse blocks be transparent to read() and just return 0's... the read call returns 0 length when reading the sparse block. I think. James
