Do you know the nature of these files? You can determine this using `lsof`, as described in this DevForums thread.
[Rick sent me the `lsof` output via email.]
The `lsof` output shows 241 (!) file descriptors used for TCP sockets, all to the same host. That’s /way/ too high. Each session should have its own internal limit to the number of connections it opens to a given host; you can pin this using `HTTPMaximumConnectionsPerHost` (which is typically 4) but it’s also pinned by the internal workings on NSURLSession. It seems that this pin has come unstuck )-:
How you modify `HTTPMaximumConnectionsPerHost` at all?
I had it set to 24. I tried setting it to 4, but I still get the problem. Note that set at 24, it works in iOS 9.3. -- Rick Mann rmann@latencyzero.com _______________________________________________ Do not post admin requests to the list. They will be ignored.
