Historically, this problem has been caused by empty segments. Inserting translation into these segments solved the problem.
Even if it was copy source to target (in the event those segments dont actually require translation)

I've seen this happen  if the empty segments in question are structurally dependent on within the document structure. 

I hope this points you in the right direction
