Floating Flow sim license not available.....

We have a dedicated node for running simulations. Only 1 eng uses the Flow sim license, connects to the sim node and runs sim's. Having completed a sim and logged off the node, he cannot not pick up the license on his own workstation until rebooting.

The License Manager showed the license not in use / available.

Anybody seen similar?

Thank you.
