ESP8266: CIPSTART failed?

Had this go south today, this time as client:

Uncaught Error: Unlink already registered
 at line 2 col 22
" already registered");g[a]=b}
                      ^

                               ^
in function called from system

then:

>Uncaught Error: CIPSTART failed
 at line 1 col 223
...d 0,Error("CIPSTART failed");}
                               ^
in function "d" called from line 1 col 16
{e=void 0;d&&d()}
                ^
in function called from system

Like before, after this two attempts at initialization are required before the ESP will work again.
