Couple things to check.
Payload size, are they different between a logged in user and guest?
Which page is this happening on? All pages or just a specific page?
Do you have any custom plugins?
We are using this plugin: https://github.com/julianlam/nodebb-plugin-session-sharing
We changed our user ids from int to guid and now of course the user mapping of the session sharing plugin creates new users.
How can we replace the old int ids with the new guids?
