Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

What actually happens when the game crashes? Do you get an error message, or does it simply close?

What makes you think it's a memory leak issue as opposed to a crash? How much memory is it using? Can you provide a screenshot of the task manager while playing?

Do you need to keep playing consistently in order to get these crashes or will it continue if you reboot the game?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
