UiPath.Service.Job.Start(IUserCredential credential)

Hello,

I am in the process of deploying a attended process on a call center.
This concerns approximately 200 attended licenses.
I encounter a lot of errors in the jobs. Out of 150 jobs I get 100 errors of this type:

Info: Un processus de premier plan est déjà en cours d'exécution. Seul un processus de premier plan peut être exécuté à la fois.
RemoteException wrapping System.InvalidOperationException: Un processus de premier plan est déjà en cours d'exécution. Seul un processus de premier plan peut être exécuté à la fois.
at UiPath.Service.Job.Start(IUserCredential credential)

English translation :

Info: A foreground process is already running. Only one foreground process can be executed at a time.
RemoteException wrapping System.InvalidOperationException: A foreground process is already running. Only one foreground process can be executed at a time.
at UiPath.Service.Job.Start (IUserCredential credential)

From what I understand, an agent is trying to run the same process twice. I don’t think I’m the only one with this error. However, the target user is agents not familiar with IT.

Can you give me feedback?

Thank you
