You are backing up a very active filesystem. The dump with tar works
in two stages, make a list of everything to be backed up, then back it up.
Where you get messages about "cannot stat", that file was removed between
the two stages. Likely it was a temporary file, such as one collecting an
incomming mail message, before renaming and placement in a users mailbox.
But it could also be a file that someone just happened to "rm" before tar
got a chance to back it up. This situation is one of the reasons tar is
generally run with the "ignore-failed-read" option.
Where you get messages about "file changed", again the file system was very
active and that particular file changed either between the time tar started
reading the first byte and finished reading the last byte. The accuracy of
that ONE file is definitely suspect. But it should not affect the rest of
the backup.
I'm not familiar with the "socket ignored" messages.

Those are the commands reporting the above events.

Amanda rewinds the tape when it needs to. Otherwise it leaves it alone.
If you want the tape rewound after amdump, add an "mt rewind" command
to the nightly cron command that runs amdump.
