The problem is that the process take hours of compilations, and tests are not easy to do. Anyway, I will enrich my « minimal » code to my « full » code in order to find the difference… and the problem. I will update the thread as soon as can.

My over 700k object graphics example, processed several times (repeatedly, over several pages with modifications) took less than one minute to process. In fact, each graphic took almost as long to render from the pdf as it did for metapost/lua to process. Alan

Dear List,

I’m running into a problem in Metapost (using Context of course!) creating (I think) too many objects; I got this error message:

variable instance identifiers exhausted

The max value for that is 2^31, or about 2 billion (and some change). Are you sure you do not have an eternal loop in your source? The number of objects I have is clearly less than 2^31, so my problem is elsewhere then. I do not think this a loop problem, because the same code runs ok for 15 000 objects, but give an error for 18 000 objects. I’m working to build a minimal example. Thanks a lot for the help ! Much appreciated. Fabrice.

At the ctx meeting we've seen examples of graphics using many more than 15K that processed fast and also (maybe surprisingly) could be previewed quite ok. So, indeed a minimal example would help.

No, it was more than 700k objects! Alan ;-)
