I ran into this a long time back under 4.5 (currently at 5.1/MP2) on some
random Solaris 8 hosts. This issue is a bug in the AIO driver and a Solaris
patch (109384-07 or higher) seemed to address this issue. According to a
Veritas tech I spoke with at the time of the problem they indicated that the
entire file was in fact being backed up and there was no risk of data loss.
The message comes from a timing anomaly within the AIO driver when the
backup process is querying inode data for the file statistics and getting
bogus or garbage data returned. Apply the latest AIO driver patch and the
messages should cease to appear.
