I believe that the 200 bit indicates that a core file was produced, and 13 is probably a signal number (13 octal equals 11 decimal which would be SIGSEGV). I am not sure whether the size of the file system is itself the cause, I have been using dump(8) to back up a large (currently 6.7TB) volume to tape for years (several tapes, actually) and it works fine, although that system is still on 6.1/amd64. I looked in CVS and didn't see any obvious diffs between 6.1 and 6.6 that jumped out at me as potential causes, so perhaps the issue has been latent for a long time and I haven't seen it because it's triggered by the particulars of one or more files rather than the overall file system size. Maybe if an individual file gets too big, or is too 'sparse' or something? -ken
