Rsync problem with NBO 2.0.5

Dear,

I'm still having a big problem with Rsync.

I installed a NBO vers 2.0.5 I can sync the SYS volume and start the DATA
volume but after few minutes I got the following error message.

01/17 01:14:31 [26228] SendBuffer: Error fd = 205 peer socket closed
01/17 01:14:31 [26228] rsync error: error in socket IO (code 10) at
io.c(1765)

I already restricted replication bandwidth to 100 Kbps but it still not
working.

Could you please tell me if you have any experience and what can I do to
sync all data.

Many thanks for your Help
