If the original undercloud installation was done on RHOS 7.2 then the timeout may be due to bug 1305947. To check, look at the file /etc/heat/heat.conf on the undercloud; it should have a line like:

rpc_response_timeout = 600

If not, then add one and restart openstack-heat-api and openstack-heat-engine.

Comment 7 Zane Bitter 2016-07-25 13:31:37 UTC
I should have said OSPd 7.2 (not "RHOS" 7.2).

Comment 10 Steve Baker 2016-07-27 22:00:49 UTC
Could you please also confirm that heat.conf has the following setting?

  max_resources_per_stack = -1

This is set for new installs by puppet, but not for minor 7.x upgrades.

This setting dramatically reduces the load on heat for all stack operations.

Comment 11 David Hill 2016-07-28 14:49:03 UTC
max_resources_per_stack = 1800.   We'll be trying -1 and keep you posted.  Thanks.

That did it... Thank you so much!  Now deploying the overcloud takes 5% of the initial time.
