I have installed server neo4j on linux. It was working before, but now it crashes every time. I initiate Neo4j via ./bin/neo4j start. It loads up. I access via web browser at 7474, but get this error ""Neo.DatabaseError.Transaction.TransactionStartFailed". Abridged log and debug output below. How to fix this?

This is the error from the neo4j.log

> INFO Starting...  
> WARN The client is unauthorized due to authentication failure  
> ERROR Client triggered an unexpected error (Neo.DatabaseError.Transaction.TransactionStartFailed] : The database has encountered a critical error and needs to be restarted. Please see database logs  
> ERROR Failed to start Neo4j: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase\*\*\*' was successfully initialized, but failed to start. Please see the attached cause exception..  
> ...

This is the error from debug.log:

> Suppressed : org.neo4j.kernel.impl.store.UnderlyingStorageException: Failed to flush  
> Cause by: java.io.FileNotFoundException: $NEO4j\_HOME/data/database/graph.consume\_complaint.db/neostore.counts.db.a (No such files or directory) (edited)
