Issue running Tests which Integrate with NHibernate/SQLite Under Ubuntu/Mono

I have some unit tests which use NHibernate and an In memory SQLite db, now these tests pass 100% of the time running from CLI under both windows and linux using my nant build file.

Now the same build file running on team city randomly fails with this error:


NHibernate.Exceptions.GenericADOException : could not insert: [eTrustMax.Domain.Customer#20fbfa7a-1356-4089-a3b5-9dc7000cbf09][SQL: INSERT INTO Customers (Name, Id) VALUES (?, ?)]

    drop table if exists Customers


    create table Customers (

       primary key (Id)
    )

NHibernate: INSERT INTO Customers (Name, Id) VALUES (@p0, @p1);@p0 = 'Test', @p1 = 20fbfa7a-1356-4089-a3b5-9dc7000cbf09

-------------

I am not sure why it seems to randomly loose the connection to the in memory db, if I were to re run the build it would then pass fine, sometimes it might need to be run a couple times, seems very random.
