I have replaced all of my HPUX sshd's with versions that do not
SA_RESTART and have not had the problem again.

However, the problem with a hung scp was _very_ intermittent and would
sometimes take several days to appear.

Whereas the interactive ssh sessions always required an extra keystroke
to close the connection and now since the removal of SA_RESTART that
problem has gone away 100%.

If i have a scp process that hangs again with the new sshd i will update
you.

Thanks,
