One Workstation shows it is using more than One License from Enterprise License Manager - ELM

How could a single workstation or User be using more than one license?  

If a user's workstation crashes or becomes disconnected from the network unexpectedly, sometimes the license is not returned to Enterprise License Manager correctly.  The vendor daemon screen may show the same user using more than one license until the license manager determines that the first license is actually no longer in use.

Each user signing into a particular workstation grabs his or her own license from Enterprise License Manager, these would be broken out in the Hosts screen by User name.

If a floating license is not properly returned to the Enterprise License Manager by a workstation, it simply expires within ten minutes to an hour or so and is returned to the pool.  The workstation would remain authorized because the second license it is using remains valid.
