rsync - Aug 2008 - rsync hangs after aborting a process

Greetings.  In testing an rsync backup script I'd created, I made a mistake
and aborted the running script with a ctrl-C keyboard interrupt.  The
command that was running at the time was as follows:

${RSYNC_CMD} -aNHAXx --protect-args --fileflags --force-change
--rsync-path="/usr/local/bin/rsync"
<username>@<my.server.com>:${CPY_SRC}
${CPY_DEST}

The expected data transfer was somewhere in the range of 150GB, but all in
small-to-medium sized text files and images.  The transfer was aborted after
approximately 10GB of files were transferred.  

Now, whenever I try to run the same script, rsync hangs.  No data is
transferred.  I can stop the process with the same keyboard interrupt, and I
get the following message:

Killed by signal 2.
rsync error: unexplained error (code 255) at rsync.c(597) [receiver=3.0.3]

If i try running the command with a few --verbose flags, I see this:

receiving file list ... 
[receiver] expand file_list pointer array to 262144 bytes, did move
[sender] expand file_list pointer array to 262144 bytes, did move
[receiver] expand file_list pointer array to 524288 bytes, did move
[sender] expand file_list pointer array to 524288 bytes, did move
[receiver] expand file_list pointer array to 1048576 bytes, did move
[sender] expand file_list pointer array to 1048576 bytes, did move
[receiver] expand file_list pointer array to 2097152 bytes, did move
[sender] expand file_list pointer array to 2097152 bytes, did move
[receiver] expand file_list pointer array to 4194304 bytes, did move
[sender] expand file_list pointer array to 4194304 bytes, did move


I'm pretty much at a loss to explain what is happening here, or how to fix
it.  Searches on google and here in this forum have not brought up any
useful results, although I admit it might be because I have no idea what to
call the problem.  Anyone have any clever ideas, and great solutions?  

More info:
  both machines are OS X.  source is OS X Server 10.4.11, destination is OS
X 10.5.4
  both machines are running a hand-built rsync v.3.0.3, since the rsync that
ships with OS X isn't really      
    good enough

Thanks in advance for any thoughts you might have :)

Is rsync hanging or just receiving an enormous non-incremental file list
from the remote machine?  Check if the remote rsync process is accessing
the disk.

With rsync 3.0.3 on both sides, I'm surprised that rsync isn't using
incremental recursion (and printing "receiving incremental file list"
instead of "receiving file list ...").  You might try removing some
options to see which one is disabling incremental recursion.
