title: Firebird - database file shutdown error message
body: <p>I have a problem with my Firebird database. The primary key of one of the tables is referenced by another table that was actually dropped earlier. So this reference from a non-existent table was causing errors when I try to make any changes in the table data.</p>
  
  <p>So I did a backup and restore and the bad reference was gone but now when I try to connect to my database more than once at the same time I get the following error: </p>
  
  <blockquote>
    <p>database [file path] shutdown</p>
  </blockquote>
  
  <p>How can I solve this?</p>
