Somewhere along my project I seem to have introduced something that added a web server thread that holds ~40% of the cpu usage of my machine at all times. Even across restarts it will come back.

Is anything in this thread dump obvious to what I could look for to resolve it? Before this my gateway would hold at around 5-10% utilization, now its constantly at 50+

We are having a very similar issue with our gateway, was this issue ever resolved?
