Fixed In Version:	openstack-puppet-modules-7.0.2-1.el7ost	Doc Type:	Bug Fix
Doc Text:	Previously, although the haproxy is configured to allow a value of 10000 for the 'maxconn' parameter for all proxies together, there is a default 'maxconn' value of 2000 for each proxy individually. If the specific proxy used for MySQL reached the limit of 2000, it dropped all further connections to the database and the client would not retry, which caused API timeout and subsequent commands to fail. With this update, the default value for 'maxconn' parameter has been increased to work better for production environments, As a result, the database connections are far less likely to time out.

Cloned this just to make sure it doesn't fall through the cracks for 8 -- it should already be in.

Used same doc_text as related BZ.

Comment 5 Alexander Chuzhoy 2016-02-02 17:52:55 UTC

Verified:
Environment:
openstack-puppet-modules-7.0.1-2.el7ost.noarch

The default section in /etc/haproxy/haproxy.cfg has now the line:
defaults
  maxconn  4096
