For a v9.4.3 Umbraco site hosted in Azure, we are seeing the examine indexing jobs randomly shut down. This means that content changes are not getting updated in the Index and reflected in the site search.
Looking at the logs, when a user saves an item and the Examine index should be updated we see these logs:
INFO Examine shutdown not registered, this AppDomain is not the MainDom, Examine will be disabled
INFO Suspend indexers.
I think this would mean that the instance is loosing the MainDom lock at some point before the save, however we can’t find anything in the logs to show that that happened. It also is only one Azure instance so there isn’t anything else that could take the MainDom from this server.
Restarting the site will fix everything, but we don’t know why it’s getting turned off. We also have all the recommended Azure Settings set already.
Does any one have any ideas as to why this could be happening?
