Hi, We deployed a new version of our app today which now users FNH to configure our NHibernate instance. We were previously using L2S.
We are seeing random errors coming from our server farm which are being raised by FNH, mostly during the buildings of the mappings. The errors are not consistent (it may be 1 or 2 per thousand requests) but it's enough to cause an issue. These FNH errors then lead to NHibernate errors which I believe is because the mappings are in an inconsistent state. Here's an example Call Stack ---> System.ArgumentException: The node to be inserted is from a different document context. at System.Xml.XmlNode.AppendChild(XmlNode newChild) at
