Duplicate Actions and events in same session with UserID

Hi

We have installed Matomo 3.7.0 and we hava an importat problem with actions stored for users sessions tracked with Javascript. We have duplicated tracked events and page views for the same user session. For example We have user page view duplicated in the same second and views pages twice when is imposible to see more than one time.

This does not happen with all users. We currently have a lot of traffic and We have configured the Mysql Queue plugin.
