The value NIL is not of type SB-IMPL::BUFFER.
once i get this error, it remains forever. seems like some lethal sideffect happens... after this the web server is unable to serve anything with the same error.
our new codebase is not affected by this (uses iolib), so if you can't quickly find something suspicious and as i can't give a test-case, feel free to close it...
might be due to multi-core threading.
the error comes from here:
