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.
