I'm just starting out with osrm, trying to understand how shared memory works.\r\n\r\nThe springclean option does not appear to work:\r\n\r\n```\r\n$ osrm-datastore --springclean\r\n[warn] caught exception: .hsgr file must be specified\r\n```\r\n\r\n1. Shouldn't this be an error rather than a warning?\r\n2. Is the .hsgr file really necessary?\r\n\r\nIf I specify the file as well as springclean, it seems that the springclean option has no effect. It does exactly the same as without the springclean option - the data remains in the shared memory. The key reported by `ipcs` changes, so I would assume that this reloads/replaces new data as described in the docs.\r\n\r\nIs this a bug with `springclean` or am I misunderstanding something?\r\n\r\nThanks."}}
