When the client machine loses connection with the license server while it is using the license, the license will not be "returned/checkin" to the license manager. The license manager sees the license is still "in use/checkout" by the machine from the previous connection/session. Once the machine is reconnected - this is now a new and different connection/session and a license checkout request will now occupy another/different license since the previous one is still "in use/checkout".
Try to: 1) Resolve the connection issue between the client machine and the license server. 2) Wait for 90 minutes before the license manager will automatically "release/checkin" the license if it does not receive a "checkpoint/sync" from the machine that checkout the license. This is the minimum "inactivity timeout" to "release/checkin" license.
