Recently this started happening and I have no idea why. We use a single virtual machine, Windows Server 2008 R2, with 4 concurrent licenses. While a user is working, I've noticed they are consuming 2 licenses. Has anyone experienced this behavior before or found a solution. The user may have ArcCatalog and ArcMap open at the same time but that shouldn't consume multiple licenses.
It's frustrating to have to go check in one of the licenses every time this happens which seems to be more frequently.
