I can confirm the problem.
Situation here: 2 identical HP Microservers (Debian 7, on site compiled
rsync 3.1.2, connected via OpenVPN).
SSH is used for transport.
Both machines have the correct date/time set via ntpd.
All files on Client/Server are rw and have the right owner and are
copy'able. oth sides.
The "directory to backup" is a Samba-share (I stopped nmbd and smbd, no
change). Client: 200GB, 42000 files total. Enough disk-space and memory
on both sides.
All rsync instances were killed (Client/Server) before starting rsync.
tcpdump shows me a NOP packet every 2 min.
I can provoke the error doing this:
1) Start the transfer (rsync scans *all* client files and starts sending
a file)
2) ^C rsync on client
3) "pkill rsync" on server until all rsync-processes are killed. Same on
client (just to be sure)
4) Start the transfer again, now rsync scans the top directories only
and hangs (see straces below).
Commandline:
./rsync-debug -v --archive --progress
--human-readable --delete-during \
--rsync-path=/home/backup-hugo/bin/rsync-debug \
/srv/backup-bernd backup-h...@backup-hugo.vpn:/srv/
