Hugo got stuck here in page_bundler.go:

	if err := g2.Wait(); err != nil {
		return err
	}

In my opinion, Hugo should exit with an error code

[moorereason]

Can you provide a minimal example of metadata that triggers this behavior?

I just uploaded an archive of posts to DropBox https://www.dropbox.com/s/f7d4j98lyx6xcan/Archive.zip?dl=0
Could you check it out?

[moorereason]

Many of your page titles have unescaped double-quotes inside them which is causing all of the TOML parse errors you're seeing. For example:

title = "PDF EPUB: Anne Bradstreet: Poems "The Prologue Summary And Analysis EBook Full Text  "

Should be one of:

title = 'PDF EPUB: Anne Bradstreet: Poems "The Prologue Summary And Analysis EBook Full Text  '
title = "PDF EPUB: Anne Bradstreet: Poems \"The Prologue Summary And Analysis EBook Full Text  "
title = """PDF EPUB: Anne Bradstreet: Poems "The Prologue Summary And Analysis EBook Full Text  """

However, parsing errors shouldn't cause Hugo to deadlock. We'll need more details about your setup to validate your claims.

I can reproduce this. Surprised no-one has stumbled on to this... I will fix. Thanks for reporting.

@moorereason Yes, those illegible characters are for a purpose. We host a lot of Hugo blogs on our server for customers. Having bad content from a customer should not etc... brings a whole server down due to deadlocks.
