I am creating shared memory with given name(by given file name with key value ) and creating the map in the shared region by parsing key-value from the file. First time it is ok. but when i try to do it again, I am getting following error.

terminate called after throwing an instance of 'boost::interprocess::interprocess_exception'  what():  File exists Aborted
