You may have flaky hardware. I once had bad RAM that was sensitive to the particular way the memory was accessed. The only problem it ever caused was that FTP downloads to that machine were *always* corrupted. I never, ever had any other problems. Memtest86 discovered the bad memory module, but I had to let most of its tests run for a long time before one of the later tests found the problem. Memtest86 got forked; there is also Memtest86+. The two tests are somewhat different now, as development has continued independently on both of them. For complete coverage you probably want to run them both. The tests will take a long time, but let them run to completion. These tests not just your memory, but also your CPU, memory controller and motherboard. You might also have some bad data on your hard drive. Every hard drive vendor offers boot floppy and often also CD ISO images for low-level diagnostic tests. Download the image for each of your drive, make a disk from it, boot the disk, then run all the read-only tests for each of your drives. >From time to time it's a good idea to do a complete backup, then also do the destructive tests on your drives, then restore the backups. It exercises the bits on the drives, you see, thereby preventing them from getting flabby and out of shape. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quixote@xxxxxxxxxxxxxxxx -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
