rsync - Nov 2004 - Urgent: rsync hangs with large directories from windows

Hello,
I get hanging rsync-processes while synchronisize windows to linux, starting 
on linux.

The problem is not new, I found some mails in this list (archive) and on 
http://www.mikerubel.org/computers/rsync_snapshots/#Bugs too.

Example of the command:

rsync -e 'ssh  -i /backup/data/servers/identities/backup.W2000Server -p 22
-x
-oForwardAgent=no -oClearAllForwardings=yes' --archive --delete --backup 
--numeric-ids --backup-dir=/backup/data/incoming/W2000Server/Daten/ 
backup@192.168.0.7:"D:/Datensicherung/ /backup/data/current/W2000Server/
Daten/"

I do read the source-code a little and I thought, it would be nice, to rewrite 
some parts of the code. But first I want to know, if somebody knows, where 
the point of failure is. I could try to look for details, if I get some more 
informations about the error.

Because there are no problems between two linux-systems, I think, there are 
errors in the cygwin-sources or in compiling the rsync.exe.

It would be great, if you can help me to get in, to find out more details.

Thank you in advance

That is not yet known.  I can't preproduce the problem locally, so I
can't debug it.  One industrious user provided some system call
information leading up to the hang, and it looked like rsync was in the
right state to continue, but nothing was happening.  The only thing we
don't know is if there was any outstanding, unflushed data in the output
buffer (which is one possible way that rsync could hang).  If that isn't
the problem, then the bug might be external to rsync.  Since rsync
doesn't hang in daemon mode, I'm leaning towards the external-to-rsync
explanation, but it might still be rsync's problem.

Any help you can provide in tracking down this problem would be much
appreciated.
