Typically there are several possible causes: You are using a load balancer with ASP.NET session routing not enabled You have the IIS application pool set to recycle during the import period Someone logged in and out of Spira using the same credentials as the importer You are running multiple imports at once using the same credentials Regards Adam Mon, 29 Aug 2016 14:02:26 -04002016-08-29T14:02:26-04:00/Support/Forum/spirateam/issues-questions/1525.aspx#reply2734
