Use commitAndBegin, a bit faster because it does the
commit and gives you a new transaction in a single
call to the server.

Were you doing a local or remote repository?  It
sounds like the underlying files are closed but the
repository is still trying to access them.  The image
shutDown/startUp code closes/opens the repository,
disconnects/reconnects all sessions, so something got
out of sync.

Try 

  MagmaSession initialize.
  MagmaRepositoryController initialize.

and should clear out Magma's startUp/shutDown lists
that should then allow saving of the image.  You
should be able to reopen them and continue working.

Beyond that, a stack trace would be most helpful.
