Suddenly Problems with Data Replication via VPN

[To-M]

I would also look at the rsync.log as well and look the date that it happened in the log to see if there was another error that happened just before the error 12.

Strange, the last entry in rsync.log is from 2011/02/09. Why that? Where can I get actual log data?

Is the date set ok in DSS?
Events will be logged in rsync.log on destination, is it the one you are checking?

[prahn]

Yes, the dates are set ok on both DSS servers, I just confirmed this. But of course I was looking on the source DSS for rsync.log!
On the destination there is a log, but it is not really helpful:

Does the 2-hour-time jump means anything? I started this rsync manually at 21:52, now it's around 30 minutes later and rsync is still running on the source machine. But in fact, it looks like nothing is happening anymore... please look at the attached screenshot of my traffic monitor. After around 10 minutes, rsync stops producing traffic... :-(
