Description Andy Grimm 2015-06-17 19:19:23 UTC

Description of problem:

When our nodes boot, it takes a very long time for all of the gears to start.  I just found one contributing factor to this, which is that we do an "unidle" call for every gear, which in turn calls oo-httpd-singular graceful.

In addition to making start-up take longer, this can cause many small outages for the apps that start first.

Version-Release number of selected component (if applicable):
rubygem-openshift-origin-node-1.36.1-1.el6oso.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create a node with lots of gears
2. Stop the node 
3. Start the node
4. grep -c oo-httpd-singular /var/log/openshift/node/platform.log

Actual results:

oo-httpd-singular ran once for every gear on the system

Expected results:

All of these gears were simply going from stopped to started at boot time.  There were no apache reloads required.

Comment 2 Yan Du 2015-06-25 02:29:16 UTC

Test on devenv_5556

Create about 50 gears on the node, and there is no apache reloads required after stop and start the node.
