Don't know why it is happening, but here is what I think is happening.

The data from your dumper program, dump/ufsdump/tar/???, passes through
a program that duplicates the entire data set and sends each through a
separate data stream (pipes/sockets/...).  Similar to the unix "tee" program.

One stream goes to the holding disk/tape drive.

The duplicate stream goes to the undumper program to generate a table
of contents.  This TOC is massaged and becomes the index for the dump.

For some reason this second stream is unable to write its output (or
temporary files).  This could be a permission problem, a wrong path
with missing directories, a full file system or ???
