Oisin, you made no comment on soils, but it appears likely to be either
in a container or a limited soil scape at the nursery.

From the description, I would suspect brash/brittle wood as a
possibility. Here's a link with more on that. It's old, but it still
applies. Nutrient deficiencies could be a cause of brashness, and I've
seen this in some trees where it is totally unexpected. Consider soil and
tissue tests.

  Thoughts please.

  I have been looking at a large swamp cypress (25m tall, 125cm DBH).
  It was previously twin stemmed, but one of the stems was truncated at
  4m. Image attached.

  In the past few years, it has shed several branches - around 2 to 4m
  long, with basal diameter up to 150mm. After each occasion, I have
  inspected, but have not found any sign of disease, dysfunction that
  might alert one to further failures. I suspect, this may be something
  typical of the species and age. Does anyone have knowledge or
  experience of this? Also, any ideas on what pruning might be
  reasonably carried out to reduce the risk of branch failure - the
  short side branches do not seem to lend themselves to lateral
