Moving my very old posts from old engine I've found interesting problem on increasing backlog from 128 that is inappropriate for loaded system to something more suitable. Long time ago (in 2010) an only way I found to do this was to apply the following patch
> diff -u /usr/lib64/erlang/lib/inets-5.5/src/http_lib/http_transport.erl http_transport.erl --- /usr/lib64/erlang/lib/inets-5.5/src/http_lib/http_transport.erl 2010-09-28 12:45:42.000000000 +0300 +++ http_transport.erl 2010-12-08 17:57:42.759407719 +0200 @@ -218,7 +218,7 @@ get_socket_info(Addr, Port) -> Key = list_to_atom("httpd_" ++ integer_to_list(Port)), - BaseOpts = [{backlog, 128}, {reuseaddr, true}], + BaseOpts = [{backlog, 10000}, {reuseaddr, true}], IpFamilyDefault = ipfamily_default(Addr, Port), case init:get_argument(Key) of {ok, [[Value]]} ->I wonder whether this is still true.
