I apologize if this is the wrong place to ask this, let me know if there is someplace better.

So, when doing a `mdb_copy -c`, I've run into the error message:

mdb_copy: copying failed, error -30784 (MDB_INCOMPATIBLE: Operation and DB incompatible, or DB flags changed)

When looking at the mdb_copy man page, it says that mdb_copy with compaction might fail if the database has a 'page leak'.

Since that appears to be what has happened... can anyone tell me what that means?  Does this mean that the data could be corrupted?  How do I fix this?

Thanks!
