Include Oracle stored procedures

When setting up the connection I selected "Include Stored procedures . . .". LinqPad (& in my case) goes off and tries to populate. After about 30 minutes I get an error. If I don't check the "Include Stored procedures . . ." checkbox then everything populates without error. How do I get to see stored procedures?

This is the checkbox I am talking about

I am using LINQ to DB version 4.1.1 with LINQPad 7.

Thank you.
