When I open document in more than one tab the original throw an error.

This is normal behavior as it is a way to protect against opening and editing twice the same document and overwriting some changes.
You can avoid this behavior at your own risk by adding this to the web config:
<add key="DoconutUnSafeMode" value="true"/>
I hope this helps.
