Hi, here is a copy from our main README file:

Error internalState: database is in inconsistent state and cannot be used

Blockbook was killed during the initial import, most commonly by OOM killer. By default, Blockbook performs the initial import in bulk import mode, which for performance reasons does not store all the data immediately to the database. If Blockbook is killed during this phase, the database is left in an inconsistent state.

See above how to reduce the memory footprint, delete the database files and run the import again.

Check this or this issue for more info.
