This is probably due to the sequence being reset somehow. Have you
dumped/reloaded recently? Did you manually back up or copy the table?
What is the exact error message that you see? If it tells you the
duplicated value, is it very old, perhaps 1 (indicating a reset of the
sequence)?
Note that, by "reset", I do not mean "overflow". I mean that the
sequence might have been recreated somehow.
Try to provide more detail in your bug report. See:
