GitLab Activity section shows recent changes with a big delay

Question

Since I have upgraded our GitLab CE to 8.6 It stopped showing the recent changes for example in Activity section also not showing latest commits for MR's.

Right now running the up to date version (8.6.4) still the same issue.

As you can see below the Check looks fine
