Is there a ship limit?

If there is one, I've never hit it, nor seen any of the AI hit it?
How many ships did you have? You can certainly have dozens, so I'd look to you not having a positive cash flow and ending up underneath -500BC and thus unable to produce anything until you get out of debt?

The more I encounter the problem the less it looks like a 'limit' problem. It occures late in the game when I can build a constructor in one turn. At that time, I can't switch production on that planet. I can select a different ship and it will appear in the 'center' but its name will not appear below where the selection is made and it will not switch production from the constructor.

Do you have room in your "orbit"? I know if your planet's orbit is full, it won't produce any more from that planet until you launch some.

If there's a ship limit, it's broke:

A Lobos, I have auto launch on. I did have several sitting on a starbase guarding the planet.

yea the number of ships you can have is only limited by your budget
