@ERROR: max connections (2) reached - try again later
rsync: connection unexpectedly closed (0 bytes received so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(359)

There is no rsync max connections in rsyncd.conf
Used between win2003win2003 ( long delay ) using cwrsync1.28

Any Idea? Thanks
