Earlier I posted the following error:A document that runs fine underConTeXt ver: 2015.10.09 21:28 MKIV beta fmt: 2015.10.11 int: english/englishsuddenly doesn't underConTeXt ver: 2015.12.22 10:50 MKIV beta fmt: 2015.12.27 int: english/englishmtx-context | fatal error: no return code, message: luatex: execution interruptedAt first I thought this was due to a new version of ConTeXt. A mistake, it now seems. I encounter the same error in an earlier version. It seems therefore a problem already present in either LuaTeX or ConTeXt.The error must be related to the placement of floats witness the following fact, typesetting the same document with only a difference in float-placement:No error: \startplacetable[location=here,reference=tab:beaufort,title=Beaufort tabel]Error: \startplacetable[location=page,reference=tab:beaufort,title=Beaufort tabel]A further observation: the item placed is nearly filling the page. Making the item somewhat smaller avoids the error, even if its the only item on the page.I did not succeed to compose a minimal example, in my experience the occurrence of the error seems too unpredictable. The actual project is far to complex and too big to be of use for debugging.I sincerely hope someone can solve this. The error brings to mind a similar problem experienced years earlier. It then was a problem of a null object in the pdf-section, if my memory is correct and I think Taco has solved that.Hans van der Meer
