:(  I was hoping against hope that this wouldn't be the answer ...

I think that the hard limit onSolaris must be 256, because ulimit -n 200
seems to have the appropriate effect of making Zope complain about
"too many open files" ... but anything higher than 256 gets
a "File not found" ...

Let's try this from another angle ... why does Zope need to open so
many files just to process a *large-but-not-really-large* POST?

Can I change something about the way the form is set up (I use
a lot of ":records") to circumvent the problem?
