Severe performance degradation in HTTP Server with keep alive connections

[knopp]

We're experiencing problem with the HTTP server. Each HTTP request with keep-alive connection blocks thread until the connection timeouts. With enough concurrent requests, the thread pool runs out of threads and all new requests are blocked until the oldest connection timeouts.

I think instead of blocking the thread, the thread should be returned to pool and select should be run on idle keep-alive connections.

Is this a known issue?

Same issue for me there. I had to close manually the connection on the client side to avoid having too many threads in the thread pool.
