The downtime would depend on the size of the site as all the caches and examine indexes are rebuilt. But if I have an issue it's usually pretty high on my list of things to try if something goes wobbly.
So delete your umbraco.config file, clear your App_Data/TEMP folder, then restart your site.
You have the Umbraco logs in App_Data/logs, which might give some extra clues.
It something that others have as well.
Need to dig a bit more about the issue together with Umbraco.

When creating a new document type and template Umbraco crashes
Hi,
When I create a new doc type with template (or without) it crashes Umbraco. I see this error: Failed to retrieve data for content id XXXX.
Googled the error code, found topics with different outcomes.
The site stops loading, frontend is not working anymore and backend is extremely slow.
Tried to re-index the content from the backend. Then deleted the doctype and template, re-indexed again and now it started to work again.
Any ideas would could be causing this and how could I get this resolved?
Need to add a new doctype for my site asap.
Many thanks,
Laurens
This is in Umbraco v7.5.9
Nobody? This rather a big issue that it causes Umbraco to crash... :s
Hi Laurens,
A few things that might help people answer.
Hi Anthony,
Thanks for you reply.
Many thanks,
Laurens
The downtime would depend on the size of the site as all the caches and examine indexes are rebuilt. But if I have an issue it's usually pretty high on my list of things to try if something goes wobbly.
So delete your umbraco.config file, clear your App_Data/TEMP folder, then restart your site.
You have the Umbraco logs in App_Data/logs, which might give some extra clues.
Hi Anthony,
With restarting the site, you mean restarting IIS or the Umbraco backend Indexing rebuild?
And with downtime, I actually mean that site is offline and can't be viewed?
Thanks,
Laurens
Yeah restart the site in IIS.
And it will be down just while those caches and indexes are rebuilt, but the length of time will depend on the amount of content on the site.
Also could be worth bumping the version number in the ClientDependency.config by 1 at the same time.
So before the restart, increment the ClientDependency.config by 1.
It's a big site, so I would need to find an out of hours window to do this.
Thanks!
Hi,
Just happened again on it's own this time... From what I could find in the logs
I see that this is happening:
So according to this link: https://our.umbraco.org/forum/using-umbraco-and-getting-started/80488-recurring-application-shutdown-issue-on-umbraco-753
It something that others have as well. Need to dig a bit more about the issue together with Umbraco.
Full log from start of the error:
Ok, so we've removed KB3000850 and site doesn't stops that frequent anymore.
Also increased the max recompilation limit from 15 to 50, but will increase it to 100.
Upgraded to V7.5.11.
TL;DR
It still happens, but the site stays online and we don't loose connections anymore. So perhaps in the near future this bug will be solved completely.
have you tried disabling the modelsbuilder ? as suggested in the post you linked to https://our.umbraco.org/forum/using-umbraco-and-getting-started/80488-recurring-application-shutdown-issue-on-umbraco-753. That worked for me.
Hi Christoffer,
Yes I did and it stopped my site from working :p
Resulted in a 500 server error and stopped the app pool completely.
is working on a reply...
