Five customers? Really? Of course the issue was nothing of the kind. “The responses simply meant that there were already five sessions running on the terminal in question,” defined Eric.
All the person needed to do was choose one to make it lively. Instead she stewed till the system housekeeping routine robotically signed out of a number of of the periods. A course of that might take hours.
