We are getting issue in Sitecore Index while publishing.
When we checked Jobs found there are multiple sitecore index and custom index in "running state". And due to this item which we are publishing are not getting indexed however its publishing but not updating web index. We also tried multiple times clearing event queue from the database. But not write solution to go again and again and clear event queue.
