I've noticed some odd behaviour in the nightlies of late (currently using 7035), where by if a connection is let idle for a long time (perhaps 30 minutes or more) when I then try to perform an action (usually a file upload by "save" in an editor) I get an error message from the browser which says:

I/O Error: Cannot read file attributes
Unexpected end of sftp stream.

I get the option to "Try again" (or Cancel). So I click try again and typically it will work - although sometimes the browser will just show an empty file listing, requiring a manual refresh.
