I'm preparing quite long presentation -- nearly 3000 sides, 900 figures (500 distinct PNG files). I'm using ConTeXt MkIV installed using minimals (2010.03.12 19:49). Recently I'm hitting MetaPost capacity limit on expansion depth:

!mplib : mp terminal: ! MetaPost capacity exceeded, sorry [expansion depth=10000].

Increasing expand_depth in texmf.cnf and regenerating formats with context --make doesn't help. expansion depth is still at 10000 in error message.

This is because recursion in metapost takes place on the C stack, and that does not allow growth. But do you really need 10000 expansion levels? That seems a little weird. Best wishes, Taco

I don't see where this could come from. If I split document in half both parts are building fine.

It could be a bug in mplib then, but I can't test that without an input example. Can you create me one? (it could consist of one massive \dorecurse call, I assume?). Best wishes, Taco

Trying to prepare minimal working example of this problem I isolated it in the process. There were 3 MP graphics each one used once on each page. After change them from

\startuseMPgraphic ... \stopuseMPgraphic and \useMPgraphic

to

\startreusableMPgraphic ... \stopreusableMPgraphic and \useMPgraphic

error messages disappeared.

if that can be used it's always better (more efficient) but it's anyway strange so there is an issue in your graphic ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
