You don't mention the type of switch you have encountered this on but I
have run into this before with some HP switches.  After getting chastised
by the admins for bringing down a production switch with a scan I asked
them what firmware version they were running on the switch and found out
they were running an older version of firmware that had known issues.  We
scheduled a firmware upgrade and another scan indicated no more problems.
