The GitLab Activity section shows recent changes with a long delay

Question

Since I upgraded our GitLab CE to 8.6, it stopped showing the latest changes, for example, in the "Activity" section, the last commits for MR are also not displayed.

The current version (8.6.4) is working right now, the same problem.

As you can see below, the check looks good

Tried to:

1. Restart GitLab
2. Clear cache

UPDATING UPDATE TO THE LATEST VERSION HELPED
