There is a problem with maximum size of one scrap. Because Metapost creates vector images of scrap after scrap which are than connected together and exported to TeX and PDF. The maximum for one image for metapost is app. 5 m. 

So the solution could be to create smaller scraps or change the scale. 

m.s.

Thanks for answering.
I found the problem nearly, my project plan is very large and a th2 file of plan is about 23000 lines, im delete most of lines and reduce it to near 5000 lines and all done without errors... what should i do now?
maybe 23000 lines cannot be parsed and processed with metapost...

Hi
I had this error recently and solved it by changing the scale of the output from 1 500 to 1 1000. I assumed  my output was exceeding the size allowable for the pdf document?

The equation I just processed has given some variable
a value of 4096 or more. Continue and I'll try to cope
with that big value; but it might be dangerous.
