Always getting Broken pipe (32) on rsync

[glennmusa]

Description

Every cron'd rsync invocation results in this message:

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1668) [Receiver=3.1.2]
rsync: [Receiver] write error: Broken pipe (32)

Files will synchronize successfully, but users could definitely be led to thinking something is wrong.

1. put a file in /groundstation
2. wait a minute
3. check the contents of logs/spacestation-sync.log
