Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of IBM HTTP Server (powered by        *
  *                  Apache).                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: A mod_cache error message is written    *
  *                      whenever a connection is aborted.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The following mod_cache error message is written whenever a
  connection is aborted:
  (103)Software caused connection abort: cache: error returned
  while trying to return disk cached data
  This can result in many of these error messages being logged
  if many connections are aborted.
  

Problem conclusion

• IBM HTTP Server's mod_cache message's log level was lowered
  from ERROR to INFO to match the severity of the message issued
  regardless of whether caching is used.
  
  This fix is targeted for IBM HTTP Server fix packs:
   - 7.0.0.43
   - 8.0.0.13
   - 8.5.5.12
