Not sure how to figure that out.\n\nBut we have a user her that is able to reproduce the problem.  On\nrequest, he uploaded a 3.2 GiB file 10 times, and 4 of the files were\ncorrupted:\n\n5/MINICPAN.tar.gz /tsd/p11/fx/import/something/5/MINICPAN.tar.gz differ: byte 3003056129, line 11432004\n6/MINICPAN.tar.gz /tsd/p11/fx/import/something/6/MINICPAN.tar.gz differ: byte 1974796289, line 7508619\n7/MINICPAN.tar.gz /tsd/p11/fx/import/something/7/MINICPAN.tar.gz differ: byte 3021012993, line 11496892\n9/MINICPAN.tar.gz /tsd/p11/fx/import/something/9/MINICPAN.tar.gz differ: byte 3052797953, line 11618011\n\nThis mean we can implement the SEEK_HOLE change and see if things\nimprove for him.\n\n-- \nHappy hacking\nPetter Reinholdtsen\n"}}
