SQLite3 does not support concurrent access with multiple connections that have writeable access. Currently SM opens database connections with full access, which causes concurrent issue. This fix includes: 1. open readonly connection whenever the write permission is not needed 2. remove code that open connections that are not being used 3. remove reattempt and loggings from previous partial fix Now all writable connections are opened and used in main thread, this can ensure no more concurrent issue.
