Upgrading a socket to TLS requires the + %% crypto module to be loaded. Loading the crypto module triggers + %% its on_load function, which calls code:priv_dir/1 to find the + %% directory where its NIF library is. However, distribution is + %% started earlier than the code server, so the code server is not + %% necessarily started yet, and code:priv_dir/1 might fail because + %% of that, if we receive an incoming connection on the + %% distribution port early enough. + %% + %% If the on_load function of a module fails, the module is + %% unloaded, and the function call that triggered loading it fails + %% with 'undef', which is rather confusing. + %% + %% Thus, the ssl_tls_dist_proxy process will terminate, and be + %% restarted by ssl_dist_sup. However, it won't have any memory + %% of being asked by net_kernel to listen for incoming + %% connections.
