Since you are not using the newest release, you should upgrade to that
to see if that fixes the problem.

Great. This tells us --line-buffer causes problems on your system
(thus it is probably not an issue with -S host1).

On my "SunOS solaris 5.10 Generic_147147-26 sun4u sparc
SUNW,Sun-Fire-V210 Solaris" it works. Both current release and
20140422.

So there is something odd happening on your system.

What is perl --version?

Mine is:

address@hidden perl --version

This is perl, v5.10.1 (csw-5.10.1*) built for sun4-solaris-thread-multi
