Hi,
I've been happily using haproxy in front of Riak and Riak CS 1.x in
production for quite a while.
I've been trying to bring up a new cluster based on riak/cs 2.0.x recently,
as you've probably noticed from the flurry of emails to this list :)
I'm discovering that if I have haproxy sitting between riak-cs and riak,
then I get a lot of errors about disconnections. Initially I thought this
must be related to pb backlogs or pool sizes or file handle limits -- but
I've played with all those things to no avail.
I *have* noticed that if I get riak-cs to connect directly to a riak
(bypassing haproxy) then everything is fine, including with the original
default request pool and backlog sizes.
I am essentially using the recommended haproxy.cfg, which has worked fine
in production elsewhere.
Any suggestions?
Error message sample follows:
2015-06-04 15:26:16.447 [warning]
<0.283.0>@riak_cs_riak_client:get_user_with_pbc:293 Fetching user re

Cheers
