Kitchen display system manages memory efficiently during busy periods

Previously, a kitchen display system (KDS) device could run out of memory while loading orders, causing the Toast POS app to crash as the KDS screen opened. Because the orders stayed on the device, the crash could recur each time KDS mode was entered.

The KDS now loads orders one at a time as it scans them, rather than holding the entire order set in memory at once. Memory stays stable regardless of how many orders a device is carrying.

How to verify

The crash occurred when the KDS screen was opened, not during service. Test by repeatedly entering KDS mode on a device carrying a large backlog of orders and confirming the app loads without crashing. Tickets should render exactly as before and this change affects how orders are loaded into memory, not what is displayed.

There is no order count at which the KDS is expected to fail. This change removes a limit rather than raising one, so there is no threshold to test against.

Availability

First available in Toast POS version 2.108.
