We're running a Spring application that uses Hibernate to connect to an Oracle database. Our site intermittently stops working due to the following Exception. Does anybody have any experience on what this issue is, and why it only occurs sometimes? We currently have to restart the app to resolve it. As far as I know, we're not configuring any kind of locale for Hibernate?
