Hi, we're facing an intermittent issue in our production envionment where longpolling/im_status seems to be timing out for users. We've been unable to replicate this error in any of our other environments. We're on v15 and have our number of workers set to 17. Has anyone else faced a similar issue? 

Below is a stack track from the google chrome console
