Client on 2015.2 Advanced, having trouble with sessions.pvk ""blowing up"". File gets large, users start having problems. We know to get everyone out, shut down the application server, rename the file, and restart but this is treating the symptom, not the underlying problem. Does anyone have any details of what might be causing this issue ? It was fine for 2+ Years on this version, just started happening in the past month. Renaming the file used to hold them for a week, now getting to be a day or less. Any insight would be greatly appreciated... TIA
