    Description

      Problems in LU-4226 indicate that the MDS allows incoming file creates with bad FIDs to proceed, even though the FID SEQ is not in a valid range. These requests should be refused by the server.

      The source of the invalid SEQ may be related to PPC clients not swabbing the allocated SEQ range correctly, but that is the topic of another bug.
