    I have set up automatic nightly lev 9 dumps to a certain partition
on my DECstation 3100 system using the commands:

	rm -f /dump/filename
	/bin/dump 9f /dump/filename /partition >& /dump/dump.log

The program faithfull executes but sometimes the file written 
has a size that varies drastically from the amount of
information read.  For example, in the log, the output of dump will be

DUMP: Estimated 15360 bytes output to file named /dump/tools/tools.lev9.Fri
DUMP: Dumping (Pass III) [directories]
DUMP: Dumping (Pass IV) [regular files]
DUMP: 4461568 bytes were dumped to file /dump/tools/tools.lev9.Fri
DUMP: Dump is done

Trying to read the file with restore -if causes a segmentation violation.
This does not happen all the time, but it will occurr reliably after
a certain tape dump at a lower level.

Any ideas what is wrong?
Thanks a lot,
Gordon Jacobs
