[arch-mirrors] Investigating questionable rsync behavior

[Easy Lee]

Hi everyone,

I noticed something strange going on with rsyncd on my mirror but I am not sure if it is an actual issue on my end. Someone able to give advice?

The rsyncd reports the following behavior quite often:

Apr 10 09:19:40 srv2340 rsyncd[31797]: connect from Y.tld (X.X.X.X)
Apr 10 09:19:40 srv2340 rsyncd[31797]: rsync on archlinux/community/os/x86_64/community.db from Y.tld (X.X.X.X)
Apr 10 09:19:41 srv2340 rsyncd[31797]: building file list
Apr 10 09:19:44 srv2340 rsyncd[31797]: rsync: connection unexpectedly closed (43 bytes received so far) [sender]
Apr 10 09:19:44 srv2340 rsyncd[31797]: rsync error: error in rsync protocol data stream (code 12) at io.c(235) [sender=3.1.3]

My rsync config:

pid file = /run/rsyncd.pid
uid = nobody
gid = nogroup
max connections = 50
socket options = SO_KEEPALIVE

[archlinux]
path = /path/to/archlinux/
comment = Arch Repository
read only = true

Is this something I should fix or is it caused by an issue on the users end?

Cheers
