Does anyone have any suggestions on processing docs with many commutative diagrams

in ConTeXt.  Depending on the method (I have used xypic and dcpic) I can do between 6 and 8 diagrams in a doc before ConTeXt crashes reporting pdftex: Assertion failed, and Window

reporting and access error. I am running MikTeX under Windows 2000.  It looks like memory

problems but I would like to be sure.  I have not been able to find a system requirements for

ConTeXt,  Also, in the process of trying to work around this difficulty I have noted that

ConTeXt is able to run the diagram making plain tex macros in eplain and taylor.  Thanks you any info you can provide]
