ns_register_proc GET /ns_return_big {ns_return 200 text/plain [string
repeat " " 32768] }
Then try several times to hit your server /ns_return_big
ns_info threads will show running threads which never exit:
{-conn:ossweb:0 -driver- -1338524752 0 1140991547 ns:connthread {1
192.168.0.9 running GET /ns_return_big 16.526732 114674}}
