Why does the opera hotel system always exit automatically?

Out of memory. According to relevant information, Opera Property Management System is a management system applied to the hotel industry. The design concept is to meet the requirements of hotels and hotel groups of all sizes, and to manage and operate hotels and properties with high efficiency, high income and high quality. However, if the memory in the Opera system is full, it will lead to the phenomenon that the Opera system cannot save all kinds of information and automatically exits frequently. This solution needs to replace an Opera system memory card with a larger storage capacity.
