failures seen on mavericks 10.9

unfs3 fails in some situations when performing a chmod on the NFS share, even when running as root. So far this has never been reproduced in Yosemite, only Mavericks. The error returned is stale NFS file handle.

is this related to my problem?

dinghy hangs for a long time and quits then with the following message bellow.
i'm on OS X yosemite 10.10.5 (14F27) with virtualbox 4.3.30.

No, this is specifically about Mavericks. I'm going to close this out, it's unlikely we'll ever tackle it at this point when Mavericks is 2 releases behind.
