Sounds like a reasonable explanation.  Is there anything I can do to try
to pin down the problem?

I understand that.  But I'm afraid I can't provide any such image.

I don't think Juniper has done anything extra-ordinary at this point

triggering the bug using the same tools as them.  Will let you know if I
succeed.
