Hi all, This happened in iOS with Objective-C language.
When we open a database(sqlite3_open()), that creates a fd(file descriptor) and when we close the database(sqlite3_close()) that only close connection and fd remain open.so when user open and close many db(or one db for many time) so many fds remain open and when fds reach to 255, app not opening any file or db. this is disclosure video : https://www.youtube.com/watch?v=uvKwko4LhWo Bug? or my silly mistake?! Thanks
