    <p>Hello,</p>
    <p>I've noticed a few times already that after running for some time
      nginx hogs a CPU thread.  The machine has 8 CPU threads, so when
      the problem happens I see in Task Manager that nginx takes 12% or
      13% (consistent with a full 1/8 of CPU power).</p>
    <p>Issuing a reload fixes the problem temporarily.</p>

    <p>Looks like there is a bug somewhere.  I wonder if it is limited
      to Windows or if it's on all distributions.</p>
