ERROR XSDG3: Meta-data for Container... -- Is this database corrupt?

[Daniel Noll]

Hi all.

I had an error opening a database and the logs showed the following error (I've
truncated out the common parts of the two exceptions, if more are needed I can
post it somewhere that it won't cause a flood.

Questions:

  1. Is this, as I strongly suspect, a corrupted database?

  2. What might lead to this kind of situation?

  3. Is there any way to recover the data now?
