Yes it is resolved. We have done multiple things in parallel so its hard to tell what exactly fixed it. 

We applied latest service pack and CU on all servers including SharePoint and SQL, started maintaining indexes and updating stats manually in addition to SharePoint. 

Then run the full crawl couple times and problem went away.
