    Subjecttcp_tw_recycle broken?
    Hey.  Developing a http proxy on fedora 9 (2.6.25) and running into a
    strange issue.

    Having the proxy set up and tear down 6000 tcp connections a second to
    the same test server ip and port,
    it quickly blows up (5 seconds) due to all 30000 ephemeral ports going
    to TIME_WAIT.
    setting tw_recycle=1 fixed the problem, and there are never more than
    a couple hundred ports in TIME_WAIT.

    BUT...

    Changing the load test to alternate between two test server ips, it
    blows up. Connect: can't assign requested address. (note I am not
    binding before hand, I tried
    and binding first to port 0 made no difference - it just blows up then
    during the bind).

    And there are ~28K ports in TIME_WAIT. For example:

    proxy_ip:30000 load_test_1:8080 TIME_WAIT
    proxy_ip:30000 load_test_2:8080 TIME_WAIT
    ...
    but most are not duplicates of the same local port.


    What. The. Heck.

    So short of rebuilding the kernel with time_wait as 1 second, is there
    any other way not to brick my proxy?
