The only other thing I can add is the following log entries from the SSH
destination:
[2013-07-30 08:51:15.41] I [gsyncd(slave):289:main_i] <top>: syncing:
file:///data/docstore1
[2013-07-30 08:51:15.1106] I [resource(slave):200:service_loop] FILE: slave
listening
[2013-07-30 08:51:20.81000] I [repce(slave):60:service_loop] RepceServer:
terminating on reaching EOF.
[2013-07-30 08:55:15.154587] I [resource(slave):206:service_loop] FILE:
connection inactive for 120 seconds, stopping
[2013-07-30 08:55:15.154911] I [gsyncd(slave):301:main_i] <top>: exiting.
Which makes sense - it's showing connected and listening and then gets an
EOF from the source server at the same time the source server crashes out
with the xattr issue.
And I must apologize to everyone - I had not realized Google was adding my
signature to the bottom every time I hit reply. I'll have to see how to
turn that off.
