Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM HTTP Server on z/OS that use   *
*                  piped loggers such as rotatelogs            *
*                  (ErrorLog or CustomLog directive starts     *
*                  with a "|" character)                       *
****************************************************************
* PROBLEM DESCRIPTION: An ABEND EC6 is logged during IHS       *
*                      shutdown when IHS has been configured   *
*                      for piped loggers.                      *
****************************************************************
* RECOMMENDATION:  Apply this fix if an EC6 ABEND is observed  *
*                  during shutdown and the configuration       *
*                  includes "piped logs" (ErrorLog or          *
*                  CustomLog directive values starts with      *
*                  a "|" character)                            *
****************************************************************
During shutdown, IHS tries to kill any children that were forked
from the parent process, including the copies of /bin/sh that
were used to launch piped log processes.  On z/OS, this can
cause the /bin/sh process to abend with an EC6.

Problem conclusion

IHS was updated to not explicitly kill the forked shell, as the
logger and shell will exit automatically when the piped loggers
stdin is closed during shutdown.

This fix is targeted for IBM HTTP Server fix packs:
 - 6.1.0.47
 - 7.0.0.23
 - 8.0.0.3

Temporary fix
