Issues with chat between 2 users

We have 2 users who are trying to chat. Whenever they do, it appears the AJAX goes into an infinite loop and does not load the chats. It’s only between 2 users at this point.

I’m afraid you are a long way out of date there so it is not going to be easy to help you if you have hit a bug. Current version is 3.14.0

Have you check your logs?
Are you using GridFS for storage?
What clients are you using? Browser, app?
