Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V8.5 and V9.0                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS   *
    *                      timers expire too early or too          *
    *                      late.                                   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Timers for request dispatch, WLM queue percent, TCP
    read, TCP write, and Local Comm async read, "may" be set to an
    incorrect value which would lead to either the timer requests
    expiring early or late.
    The exposure to his problem occurs after a Server has been
    running for 11 days, and every 10 days after, and lasts for at
    most 1 hour.
    Timers set for less than 36 minutes may be delayed by 27
    minutes during this exposure.
    Timers set for 36 to 59 minutes may expire from 1 to 23
    minutes.
    This problem was reported for a server with a setting of a
    request dispatch timer of 35 minutes (ex.
    protocol_http_timeout_output=2100).  The Server starts a few
    different timers based on this setting.  In the controller it
    will set a timer based on the request dispatch timer plus an
    additional 85 seconds.  If this timer pops and the request
    is still active in the Server, it will timeout the request with
    a BBOO0327I timeout message and may terminate the related
    servant with an ABENDSEC3 RSN=04130007.  For this 36 minute and
    25 second timeout value it expired in 25 seconds.
