Is anyone else seeing the same issue where Content Indexing stops working and needs to be manually flushed?
I believe I have narrowed down the root cause for our instance - whenever Confluence loses access to the database (e.g. we just had a database outage so routine maintenance could be made), on restoration most of Confluence appears to work fine but Content Indexing is broken. Same happened for last maintenance window. Only fix that I have found is restarting Confluence.
