I've been using rsync for some time (years) to generate many
hardlink snapshots per day; but I'm seeing an odd new problem
today.  the remote/destination host gets a file list from the
source machine via ssh, and begins to write files until it
"hangs". On this run only one file was transferred; on other
runs many screenfulls went across  + rsync --recursive --links
--perms --times --group --owner --devices --specials --numeric-
ids --protocol=29 --verbose --progress --exclude tmp --exclude
*.tmp --exclude spool --exclude *.core --exclude *.boot
--exclude *.filepart --exclude *.lock --exclude *.nobak
--exclude .RDATA --exclude /repo --exclude /sandbox --exclude
/soft/dist --link-dest=/ub0/bk/1/2008.04.29.0010.00//center
//center/ lou.grid://ub0/bk/0/2008.05.08.1051.49//center/
building file list ... 580347 files to consider  the dest host
is rsync version 2.6.9 protocol version 29 and the source host
is rsync version 2.6.9 protocol version 29  in the above run I
specified the protocol because I assumed the src
