You could use 'strace -p process_id' to see if the process is still
making system calls, and tcpdump or wireshark to see if network
traffic is happening (you won't be able to decode the contents of ssh
packets, but you can see if the sequence numbers advance or if the
other end stops sending acks which might indicate a network problem).
If you can find the file being received by rsync at the other end, it
will have a temporary name starting with a '.' and keep growing until
it is complete and renamed. If this is a large file that already
exists, it can be a very slow process to merge the differences and
rebuild the old version.
