Connected user although job ended

Hello

I have 3 machines and more robots with differents users.
Every job make connection with specific user to the machine and disconnect at ending.
My problem is that some times the user is not disconnecting from the machine although the process ended, and the machine become unavailable.

What can be the cause for this behavior?

Thanks

Hi @Lior,
Could you expand it a little bit with more details? For example how your configuration is looking like? What type of robots are those? Some data that could let us know about your environment and the setup.
