Dear gang, The [ownnumber=yes] option overflows ConTeXt's memory, and I have not found an adjustment to texmf.cnf to fix it (mswincontext 3-16, 2005). I increased the param and stack sizes by an entire order of magnitude. Other options such as [ownnumber=no] work fine. This bug is not benign:-) Please advise...
