webmachine, mochiweb and erlang,iolist_to_binary

[u a]

Hello,

perhaps i missed something, but i run in trouble using webmachine,
mochiweb and larger responses. Then i get the error listed below. Is
there anybody in the erlang universe who can help me understanding the
problem and can tell me how to fix it.

Thanks and merry christmas,
Ulf
