The more I look at this the more I am thinking there is something busted in riak or webmachine (I am using riak 1.4.10). The issue seems to be impervious to apache settings or haproxy settings and going through the source there doesn¹t seem to be many knobs to turn to adjust chunked responses. Googling for issues in web machine also turned up nothing. Maybe a pause in the return of map responses is doing it? Can riak be configured to send keepalives?
