... unless you pass it the appropriate option.

Actually, rsync is very good at finding problems with tcp/ip stacks. Is it
possible that it is finding problems in the Solaris stack?

What does strace show you on either end? ltrace? rsync -vvvvvvvvvvvvvvv
(errr... you get the idea :-) tcpdump? top? fprintf(3) and gcc? Lots of
debugging options :-)

If you don't already have a copy of the filing system on the other end, I
often use netcat and tar....

On sender: tar c /etc | nc destination 7863
On receiver (in appropriate directory...): nc -l -p 7863 -w 10 | tar x

Adding the z option is entirely dependant on the link.
