  • Closed as program error.

Error description

  • After upgrading to WebSphere Application Server V6.1.0.35 (or a
    later Fix Pack) or V7.0.0.13 (or a later Fix Pack), a delay of
    about 16 seconds for incoming SOAP administration calls from
    remote hosts might be seen under certain network conditions.
    This delay is not seen when the SOAP call originates from the
    local system.  The problem can affect both node agents and the
    deployment manager.  The problem is due to an error with the fix
    for APAR PM14986.
    
    When the problem occurs, the remote host and port associated
    with the current SOAP connection, which are only useful for
    debugging purposes, are always retrieved, even when no debugging
    is enabled.  This could cause slow performance when certain
    network configurations combined with possible issues in the Java
    SDK make these calls very slow.  The remote host and port should
    only be retrieved when debugging is enabled.
    
    To verify that your system is susceptible to this problem, run
    the nslookup command on the SOAP client's IP address on the
    system on which WebSphere Application Server is running.  If
    there is a delay in this command completing, WebSphere
    Application Server is susceptible to the problem addressed by
    this APAR.  Contact your network administrator to determine why
    there is a delay in the nslookup command completing.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V6.1 and V7.0                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: Program statements to get client        *
    *                      hostname and port may be slow if        *
    *                      the network is not functioning          *
    *                      entirely normally                       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Program statements to get client hostname and port may be slow
    if the network is not functioning quite normally (for example,
    a slow DNS). The root solution is to correct the networking
    problems. However, the program statements in question are only
    useful for debugging purpose. They need not be called when not
    in debugging mode.
    

Problem conclusion

  • The code is restructured so that the statements in question
    will only be called if debugging is enabled.
    
    The same issue has been fixed in base v8.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.43 and 7.0.0.21.  Please refer to the
