    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.
