Local fix

• ITXCQ - ITX00058479
  PB / PB
  Circumvention: None
  

Problem summary

• Users Affected:
  IBM Transformation Extender users who use shell adapter and
  audit data larger than 32k
  
  Problem Description:
  If shell or batch adapter audit is larger than 32K, which is
  data that adapter writes to stderr, the memory corruption will
  happen and process will likely crash. The most likely stack
  trace is:
  mempcpy
  _IO_default_xsputn_internal
  vfprintf
  vsprintf
  mpi_vfprintf
  postmsgV
  postmsg
  WriteAuditRec
  
  Platforms Affected:
  All
  

Problem conclusion

• Correct code in the utility adapters common library to allocate
  memory dynamically and be able to process data larger than 32k.
  
  Applies to:
  8.4.1.5, 9.0.0.2
  
  Fixed in the next service packs and releases.
