Looks like a network error or a crashed rsync / ssh process on the other side.
Can you run this rsync job again?
funny thing is i am webGUI into the Host box while doing the rsync in the gui didn't die. Also when rsync dies I can just restart job from the client no issues.
It just died again this time I kept SSH open on both boxes via putty on my win10 machine. I saw the GUI on the client side give this error again
rsync: read error: Connection reset by peer (104)
rsync error: error in socket IO (code 10) at io.c(794) [receiver=3.1.2]
rsync: connection unexpectedly closed (327642 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at io.c(235) [generator=3.1.2]
So instead of waiting i just clicked on the run button again. now i get this error.
rsync: failed to connect to 192.168.0.113 (192.168.0.113): Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(125) [Receiver=3.1.2]
BUT both webGUI's are up, and SSH is still open with HTOP running on the both showing now service spikes.
I also ran this right after it died

So i cant edit the /etc/rsyncd.conf file to add the disable reverse lookup flag.
I also went into the rsync area of the gui and added the ip address under allowed hosts and its still kicking me out.
this is the entry it put into my rsyncd.conf file
[omvlarge]
path = /srv/./dev-disk-by-uuid-1041347b-101a-4cd4-88e7-7492c379a4e6
uid = nobody
gid = users
list = yes
read only = no
write only = no
use chroot = yes
hosts allow = 192.168.0.237
lock file = /run/lock/rsyncd-omvlarge
my OMV5.x box might be dying or something
