Strannge issue with nightly rsync
I hope this is the right forum area.
Im getting a strange error nightly on one of my servers using rsync. The two servers are in the same subnet (255.255.248.0), but in different locations (Ireland & BLR). However we have an MPLS between the sites, so connectivity isnt an issue.
There is about 11 rsync's initiated at the far site (BLR) copying data to dublin at around 00:30 GMT. There isnt a whole lot of data as it is using the update option.
My issue is the first rsync every night fails:

rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)
send: spawn id exp3 not open
(file "" line 6)
Its ONLY the first rsync. To circumvent this, at the moment, i have started the first one a minute before hand, and again at its regular time. It runs fine then. Some of the scripts then run again about 9am GMT and they work fine (without the first failing).
Does anyone have any ideas?
