Sun Managers:
Thanks to all who replied with many wonderful suggestions.
I also received enough "me too, what gives" messages to justify
a general summary posting. My original message:

The solution: install patch number 100211-02 to fix the tape
synchronization problem existing in 4.1.1 (and supposedly in
4.1 as well). This involves installing a new st.o in your kernel.
Other suggestions included installing the patch to resolve psig
crashes discovered on exit from sunview. I'm a firm believer in
installing only as many patches as necessary, so I can't comment
on that approach. Solving the tape sync problem has eliminated
the tape host crashes, thanks!
Many replies suggested abandoning the -s option to restore and
manually forwarding the tape with mt. I would have considered this
option as a work-around if the available patches had not solved the
problem. All of the utilities had functioned properly prior to the
upgrade and have been installed on several tape hosts in the dept.
Installing the patch when necessary was the best solution for us.
