  ****************************************************************
  Plugin seems to pre-append content to `LD_LIBRARY_PATH` every
  time there is a graceful reboot resulting in a substantial
  growth
  for the variable.
  Frequent graceful reboots of Apache's web server processes leads
  to the overflow of plugin's `LD_LIBRARY_PATH` environment
  variable, subsequently resulting in the crash of the web
  server.
  

Problem conclusion

• The plugin has been updated to do additional verification to
  `LD_LIBRARY_PATH` before making any updates to the variable.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.26 & 9.0.5.21 . For more information, see 'Recommended
