rsync - Apr 2005 - [Bug 2628] hangs indefinitely (while listing files)

You didn't mention the client command you're running.

As for the log-data output by a --daemon, did you look in the appropriate syslog
file? or check the rsyncd.conf file to see if it is logging to a file?  You can
also use the "max verbosity" setting to increase the level of
verbosity that the
daemon will allow a client to request (since it affects the log size, it
defaults to 1).

yup, sorry, here it is:

rsync -rlptD -v -u --delete --timeout=90 \
  --exclude-from=/etc/rsync/rsync-exc rsync://server/remotedir /localdir/

I'm using --timeout now to at least let it go on on its own.

I don't have log options in rsyncd.conf. Anyway, I'd expect --no-detach
to
enable  logging to console as well. In syslog I see only:

rsync error: timeout in data send/receive (code 30) at io.c(181)

Q: Does changing the level of verbosity get rid of the hang?  (You are right
that this is not the same hang as the -vvv bug mention in the NEWS file because
that would only occur when pushing files, not pulling.)

Q: What does netstat show for the state of the connection on each host?

Q: What system call is each of the 3 processes stuck on?  (Use strace, truss, or
whatever is appropriate for your OS.)

in prev. msg forgot to mention that the number of -v seems to have no effect 
- actually that test was run with not a single -v on either side; and, btw, as
noted -v... seems to have no effect at all with --daemon.

sorry 4 late reply, I had to revert back to rsync setup for doing the test.

here's what netstat -tpn|grep 873 shows...
