I have an application using the K2Mng, and the Login function intermittently fails. This requires an IIS reset on the SharePoint server before K2Mng will accept a Login request again. This sometimes occurs as often as every 5mins or so. The exception is uncatchable in the code, although on occaisions (not usually) a pop up box appears in VS when debugging that says "System.ExecutionEngineException".
Any ideas of what is causing this and how it can be resolved? Thanks
