We have had a lot of problems with the Sun 3/260 (3.3) (4.2BSD) we have
had for two months.  The file system has gotten totalled several times.

Our Sun representative has told us that if either disk partition becomes
more than 90% full, it is normal for all files on both partitions to be
trashed without warning.  Is this right?  If it is, is there a way to
prevent more than 90% of a partition from being used?

He also said it could be trashed if a program tries to use too much
memory, for instance with large arrays of real numbers.  Is this true?
If so, how can we prevent this?

He has also said that after using doing a restore of a zero level dump,
it is necessary to immediately do another zero level dump or the file
system will get hosed again.  Is this really needed?  If so, can it be
done overnight, to /dev/null?

Please reply to me.  I am not on both of these lists.
