I had to introduce a timeout setting in Hugo 0.40.3 to bail out of potential cyclic behaviour. I suggest you run “hugo -v” and see if there are any warnings related to this.
There are only i18n warns and a lot of alias INFOs:
WARN 2018/06/18 11:16:35 No translation bundle found for default language "en"
WARN 2018/06/18 11:16:35 Translation func for language en not found, use default.
WARN 2018/06/18 11:16:35 i18n not initialized, check that you have language file (in i18n) that matches the site language or the default language.

And there are couple hundreds more of this kind of INFO messages
