Rsync stops inmid of synchronisation

[Richard Ivarson]

OK, so I called "strace -p <ID>" where ID is the pid of a running rsync 
command. Then I waited until the rsync command timed out due to the unknown 
problem which I try to encircle.

In short the problem is: two computers with WinXP_pro 32bit and up-to-date 
Cygwin are connected, and I try to rsync some folders of the first computer 
to the remote computer. However, after the sender rsynced some thousands of 
smaller files correctly (respectivly: it checked them without transfering the 
up-to-date files), it suddently stops to do anything... That's why I've added 
the "--timeout=30" parameter to the sending rsync, so that my rsync aborts 
the "offending" folders and the bash script can continue with the following 
rsync commands.


So now rsync said this:

   [sender] io timeout after 30 seconds -- exiting
   rsync error: timeout in data send/receive (code 30) at 
/home/lapo/package/rsync-3.0.9-1/src/rsync-3.0.9/io.c(140) [sender=3.0.9]


And the strace log which happened before and during the time-out is attached 
below. (I cut the middle part of it because it just repeated about 250 times 
the "_set_errno" & "fstat64" lines.)

Unfortunately the log doesn't say anything to me, but maybe some reader 
knowing the internas of Cygwin and rsync command in particular, sees more? 
Thank you very much!

-Richard
