Hello, We have been using a device which has linux operating system. We have been keeping sqlite database file in a sd-card. In normal conditions, after mounting/unmouting we use sqlite database without problem. But sometimes, randomly, we can encounter with an unmount problem: "resource or device busy". As far as I know, sqlite can cause some problems with network-mounted file systems. I wonder if sd-card mounted file system cause also this kind of error? Can you please help me? Thank you very much
