I have sitecore 8.2 Update 2 and We are working on EXM on QA environment. We are trying to import contacts using csv file. When we upload this file, Sitecore start the indexing. But this indexing does not start. We are getting message "0 of 20000 contacts are indexed". this remain same for unlimited time and never updates.
I tried to do manual rebuild "Sitecore Analytics" index. It start the rebuilding the indexes but stop in between and never completes. I tried to rebuild all indexes with List Manager but also not working. We are not getting any error in log files.
Please help if you have any solution on this?
