We have a web page we built that queries jenkins rest API's to populate some data. We used to get a list of the current running pull requests by going to the /runs/ page, but it seems like after updating to 2.222.1 that doesn't always work. 

More specifically, we used to access /runs/?start=0&limit=85 which worked perfectly fine until upgrading. Now we have to use /runs/?start=0&limit=50 or less to actually get a response back from the end point. It's also worth noting that accessing /runs/ without any parameters at all also doesn't even return.

We can also see the ton of threads from these requests that basically build, never return, and look like they aren't doing anything.
