Using my neeo remote tonight to control a device through the http binding, system became unstable. Logs seem to indicate that I hit this again. Probably related to #3702

Unsure if this is related. I'm having issues with an enormous thread count. I have over 4000 active threads of type "HttpClient-1-SelectorManager" (with different numbers obviously). All resemble:

This looks to be tied to the neeo integration addon. I removed both neeo pieces and reloaded, the count sat at 1. I added only the integration and the count jumps to over 300 immediately.

It also is throwing this:
