Just spent an hour investigating a site outage we had from midnight Saturday to 5AM Sunday (29 hours) and I'm stumped. It only affected the home page. It logged a null reference exception on this line:
Layout = "master.cshtml";
Every other page on the site was operational, even though they use the same master page.
The outage started at 00:20AM on Saturday, following Umbraco doing a number of automatic operations such as:
Booting site '"BCarm.www"', app '"REDACTED"', path '"REDACTED"', server '"REDACTED"
Creating the content store, localContentDbExists? True
Creating the media store, localMediaDbExists? True
I can see the same operations happen at 05:00AM the following day, and then the home page just starts to work again. Because I was out of the office I didn't pick up on this, and so our home page was down for 29 hours.
Any idea what's happening here? Could Umbraco's auto-reboot have run into an issue with the content store, that was resolved at the next auto-reboot?
24 hour site outage I can't explain
