Every Friday we have a film showing to members of a private film club. This means we sell a Membership card and a ticket to the film. We have 3 cashiers, 3 stations and we are all working at a furious pace. Our Patron Edge program has crashed with the pop notice (SRO server not responding) every friday. We have to re-boot to get back to working order, meanwhile the line of people is becoming impatient. Do you have any idea why we crash? Do you have any idea how we can improve this ticketing problem.
