boltdbweb get stuck, browser failed to connect

boltdbweb gets stuck and browser fails to connect local host at port specified.

@hankgao I think this could be because some other application is accessing the db file.

@MerlinVancur is correct. Boltdb doc states that a second open attempt will block, unless a timeout parameter is specified.
