It seems that the repository is corrupt.

I Renamed the Server/Repositories and restart MGServer again. MG Server recreate a new folder 'Server/Repositories' and then MG server runs well again.

It is a pity that the issue can't be reproduced now. Even if I renamed some files' names inside repositories or deleted some external spatial data files, Now MG can repair repositories automatically while restarted.

I think Mapguide shouldn't terminate itself while meeting with some non-key problems, such as corrupted repository. The repair of the repository could be finished by administrator through some tools like Maestro. If MGServer is terminated, user will have no visible entries to interact with it.
