We have issue in that objects stored in session sometimes are returned as null. It occurs after running automatic testing using 1 in 100 to 200 times. The test runs the exact same calls. The issue is on a production server running SharePoint (That I have no access to), I’m unsure of the way session is stored SQL or Session State service. The solution is load balanced in production. And most calls are done using JavaScript ajax, not callbacks “_vti_bin/solutionName/service.svc/javascript/js” (we have developed some web parts that is part of a larger solution). I wondering if we are having a race conditions, that the session is not finished setting the object before a call is done to retrieve the object (something I’m still looking into). But my question is; have others experienced session issues like we are having and what can be the reasons?
