Modelsbuilder failing to generate models due to SQL error

[clausjensen]

Note - this only happened one out of 4 times while testing installs from zip, with both sqlce and sqlserver. It happened on the sqlserver install:

When the site was installed - modelsbuilder was not able to generate models and generated this error:

Failed to build PureLive models.
There is already an open DataReader associated with this Command which must be closed first.

After triggering a generation of models (saving a document type) this error goes away but I then get a binding error trying to bind nucache content.

Republishing the content item will make this error go away as well and my content now renders.
