I ran into a similar issue recently while transferring large files (>40GB).
After a few tests, it seems - in my case at least - to be related to the
delta-xfer algorithm. The bug does not happen anymore with the -W option.

I don't know if this will resolve your issue, but you can also try looking into
these options : --no-checksum --no-compress --blocking-io. These were not the
source of my problems, but the functions they're related to might rise a
network timeout.

I hope it helps, anyways, good luck solving your issue.
