Backup Central

Hello,

If I try to run

$ rdiff-backup -v 9 -b dir linuxhost::dir

from an OS X box to a Linux box, then I get this kind of error. I don't get
this error if I use -v 8 or lower.

Regards,
Blair

you know there's no reason i can think of we would get EAGAIN from
sys.stdout.write ... unless we've set it to non-blocking somewhere?

do you have strace or ktrace or something? i don't know what OSX has in
this area... try [sk]tracing a short run with -v9 and put it somewhere i
can peer at it... we're looking for fcntl(1, F_SETFL, ...)...

Dean,

The only thing I could think of is that there's a formatting error with the
logging on either end of the ssh connection and one end closes their end,
causing the other to get something like this error.

In any case, I just tried running the command again right now to use ktrace on
and can't reproduce it, so I guess we'll "close" this issue, unless I run into
it again, and then I'll ktrace it on the spot.

Regards,
Blair
