I just ported my app to Seaside 2.8 and under production load I'm suddenly
getting a whole bunch of "There is no free space in this set!" errors.

I say a previous thread mention this
http://www.iam.unibe.ch/pipermail/smallwiki/2007-March/002656.html but it
was related to backtracking state, which I'm not currently using.

Lukas any idea what's going on here?

Here's the full error details...
