dev_seek error during ufsdump

Few days ago one of our E3500 systems become to fail its backups with the
following error message:
DUMP: Writing 32 Kilobyte records

I searched in the codeprof archives but nobody seemed to have a good
ersponse from their support staff. Also I browsed the sunsolve's archives
but there are theories mainly (that's why I call this site "unsolve" :) )
Our local Sun Support representative quoted the man page that states:
When running ufsdump, the file sys-
tem must be inactive; otherwise, the output of ufsdump may
be inconsistent and restoring files correctly may be impos-
sible. A file system is inactive when it is unmouned or the
system is in single user mode.
Well, the error message shown above was run *in single user mode* as
suggested.
1.- Environment: E3500, Sol 2.6, kernel level: 32, OBP 3.2.29, Volume
Manager 3.1.1 with encapsulated root disk, Veritas Filesystem 3.3.2 for the
rest of filesystems except for root, /var, and /opt.
2.- This backup method had been in use for about three years now.
Any ideas, clues or jokes will be very appreciated.
Many thanks in advance,
- Andres.
