This pattern has been re-occuring for at least the last 10 ftpsync runs,
which suggests that a predefined timeout is being triggered somewhere.
The rsync timeout on our side is 3600 seconds however.
Attaching strace to the currently running rsync, it appears to have
finished transferring files and has entered the delete stage. Could it
be taking too long to trawl through the directories?
Yes, it could.
I had experienced the same problem with one of my downstream mirrors. I
noted that their rsync timed out in about 10 minutes of "inactivity"
(according to strace of my rsync daemon) on the second stage. Some time
before that I set timeout in my rsyncd.conf to 600 seconds and this was
the reason why their side was disconnected. Also I have to note that
this downstream mirror had very slow disk storage.
