Earlier I posted the following error: A document that runs fine under ConTeXt ver: 2015.10.09 21:28 MKIV beta fmt: 2015.10.11 int: english/english suddenly doesn't under ConTeXt ver: 2015.12.22 10:50 MKIV beta fmt: 2015.12.27 int: english/english mtx-context | fatal error: no return code, message: luatex: execution interrupted At 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

Using \loggingall near the error is better, but of course it means that you know more or less where it happens. I have an idea where to start and stop logging. Is just \loggingall sufficient to start the log? How do I stop that logging? Hans van der Meer
