Suddenly an error appeared out of nowhere when managing groups.

"Count data for smart groups is not currently calculated. You may click Update >Smart Groups to generate it. Be aware this can cause significant server load." (screenshot 1)

When I try to Update Smart Group Count or click on Contacts of any group, there is the error:

Sorry but we are not able to provide this at the moment.

DB Error: unknown error

Return to home page.

(screenshot 2)

Meanwhile, the database is NOT down. I can access contacts through search.

What could have happened? Where do I start looking for solutions?

CiviCRM 4.7.14. on Drupal 7.52

civicrm_group_contact_cache table for some reason has exceeded auto-increment value limit (2^32).

This is possible because of nature of this table - caching, adding, removing items.

Solution is to drop auto-increment value to beginning:

ALTER TABLE civicrm_group_contact_cache AUTO_INCREMENT = 1

Detailed instructions are available in the "More detailed errors" section of the troubleshooting guide. In short: Either turn on debugging AND backtrace, which will give you a more detailed error; or view the appropriate errors in your CiviCRM log.

If you need help interpreting those errors, I suggest opening a new question here. It's also a good practice to paste the text of the error instead of (or in addition to) a screenshot of the error - it makes it easier for others to search, and easier for someone to troubleshoot.
