APAR status

• Closed as program error.

Error description

• Session ID cache demon (sidd) started twice in error at Apache
  server startup.
  This can result in a variety of different errors being issued
  when the additional process is subsequently cancelled, including
  ABEND=SEC6 U0000 REASON=0000FF0F
  EC6 FF0F
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users running IBM HTTP Server on z/OS       *
  * or Windows with SSL configured for client connections        *
  ****************************************************************
  * PROBLEM DESCRIPTION:  mod_ibm_ssl initializes itself twice   *
  * during IHS V6.x startup on z/OS and Windows.  This slows     *
  * startup down slightly and also may result in a mostly        *
  * harmless ABENDEC6 on z/OS                                    *
  ****************************************************************
  * RECOMMENDATION: Apply this fix on z/OS or Windows to speed   *
  * IHS initialization with SSL configured.                      *
  ****************************************************************
  mod_ibm_ssl was initialing itself twice during IHS startup on
  z/OS and Windows.  On z/OS, this results in the SSL session ID
  cacheing daemon (sidd) process being terminated via SIGTERM then
  restarted.  If the first sidd instance was never dispatched
  prior to catching the SIGTERM, it gets an ABENDEC6 due to not
  having a signal handler in place for the SIGTERM.  Usually this
  is harmless, but the console ABEND messages could trigger some
  automation.
  

Problem conclusion

• mod_ibm_ssl has been changed to only initialize itself once on
  z/OS and Windows.  This problem does not exist in IHS V7.0
