Older versions of rsync used to load the entire directory tree into
RAM before starting to walk it, comparing file contents with block
checksums. That could be a problem at either end. Not sure when it
was fixed to work in chunks. Also there can be very long intervals
with no activity as each end is computing checksums. If you have a
NAT gateway between devices it can time out the connection mapping -
don't know if proxmox does something like that for container network
multiplexing.
