rsync between Solaris and Cygwin

[Stephen More]

I am trying to rsync a handful of directories between Solaris and Cygwin
over a dialup line. Both are running version rsync 2.5.1 with ssh.

Most of the directories work fine, except one of the same directories fails
every time with this error:


Read from remote host X.X.X.X: Connection reset by peer
rsync: connection unexpectedly closed (5149 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(139)


Is this a known bug, can I help someone fix it by debugging it any further,
what do I need to do ?

-Thanks
