Consider an application opens a datagram UNIX socket and connects it to some address. If you will try to dump such app and the server socket for some reason will '''not''' be taken in the dumped state (e.g. -- a task holding it is not dumped) the dump will fail. You can override this behavior by allowing crtools to disconnect the client after dump and re-connecting it back on restore by the server socket path using the <code>--ext-unix-sk</code> option.
