Reversing the order will hopefully give a clue on how to proceed:
make ConTeXt create mpgraph.mp first, then the other one. If that
gets you past the error (and into a similar error: test-mpgraph.mp),
then it is probably a  number of open files limit problem. Here is
the relevant macro, with the order already adjusted :

\def\initializeMPgraphics
   {\bgroup
    \ifx\bufferprefix\empty\else
      \let\bufferprefix\empty
      \initializeMPgraphicfile
    \fi
    \egroup
    \initializeMPgraphicfile }

You can try to add --passon='-kpathsea-debug=4' in the texexec
call. All the kpathsea debug output should end up in your apache
error_log (the number 4 is for fopen/fclose traces).

If you are lucky, there may be some hint in your global or local
apache error file.


Good luck,
