Error description
IHS 2.0 CPU USAGE SPIKES AFTER CLIENT CLOSED THE CONNECTION
Local fix Problem summary
****************************************************************
* USERS AFFECTED: Users of WAS 4.0.x webserver plug-in for     *
*                 IHS 2.0.                                     *
****************************************************************
* PROBLEM DESCRIPTION: When plug-in reads 200 (OK) response    *
*                      from appserver, it also sets the        *
*                      request status code accordingly.  But   *
*                      in the case that the client closes      *
*                      the connection before the plug-in       *
*                      finishes sending all the response       *
*                      back, the 200 (OK) status code will     *
*                      trigger a loop inside the IHS           *
*                      webserver, and cause the CPU usage      *
*                      to spike.                               *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Incorrect request status code triggered the loop inside the
IHS webserver.
Problem conclusion
For the scenario as described, the request status code is
reset to reflect the cause.
