Login not possible after exception during MEF import

[apontes]

Was importing ~200k MEF files from a single folder.

At some point during the process, got this message:

The requested operation could not be performed. OutOfMemoryError : Java heap space

From this point on, cannot login anymore:

The requested operation could not be performed. NullPointerException

In the logs I found:

ERROR [jeeves.engine] - Resource : main-db ERROR [jeeves.engine] - Provider : jeeves.resources.dbms.DbmsPool ERROR [jeeves.engine] - Exception : java.lang.RuntimeException: IO Error: File corrupt: last_area_pointer at the end of the file. ERROR [jeeves.engine] - Message : IO Error: File corrupt: last_area_pointer at the end of the file. ERROR [jeeves.engine] - Stack : java.lang.RuntimeException: IO Error: File corrupt: last_area_pointer at the end of the file.
