We are running Umbraco 7.2.6 on AWS ELB with Auto Scaling enabled. We have a dedicated CMS and SQL server and two web serves by default. When new instances created the umbraco.config file get's out of sync from the CMS umbraco.config file.

New instances automatically created based on the last deployment package which does not include umbraco.config. file.

On the new web server instances the umbraco.config file gets rebuilt until the date the deployment package was created which result missing content from the client facing site.

Any content published after the deployment date wont display on the new server instances until the next cms publish.

During trouble shooting I've deleted the umbraco.config file and reset iis but it did not rebuilt the cache with the latest content.

We have to perform a publish to get the umbraco.config files updated and make the latest content to show on the site. which is not ideal.

When the application starts at the first time I would expect umbraco to get the latest content from the database and rebuild the umbraco.config file. Do the same after IIS reset. But this does not seem to be happening.

Cache Related setting in the umbracoSetting.config

<XmlCacheEnabled>True</XmlCacheEnabled> 

<ContinouslyUpdateXmlDiskCache>True</ContinouslyUpdateXmlDiskCache>

<XmlContentCheckForDiskChanges>False</XmlContentCheckForDiskChanges>

We have the following option disabled in the web.config

<add key="umbracoContentXMLUseLocalTemp" value="false" />

Can we get some recommendation please?
