If you want to have a more reliable number of visitors display in the module, consider setting up a cron job as explained here #19636 (comment)

Otherwise, increase the value of session.gc_probability in PHP setting would help, too

Thank you.

This is to complicated :). It is simplier to turn off who`s online module. Before update 3.8.4. and 3.8.5 module working fine. I guess that something in joomla 3.8.4 update make mess. Site usually have less than 10 visitors and after update numbers is several thousands or more.

Yes, there was a change in 3.8.4 to improve performance and make code right related to session. In your case, change Session Handler to PHP as you mentioned should be OK

See #19585 (comment) for additional info.

Closing again, everything is working as designed for the moment (even if less than optimal for one configuration) with further efforts to improve it ongoing.
