APAR status

• Closed as program error.

Error description

• Requests with gzip content-encoding may be trucated if the
  uncompressed size is larger than 32k.  This is similar to
  PM70771, but occurs in a new channel and is only applicable to
  v8.5.5
  

Local fix

• Set the channel property autodecompression to false.

  When the content-encoding is set to gzip and the decompressed
  request data is greater than 16K, the Application Server
  doesnot consume the entire buffered data.
  The follwing exception may be seen in the ffdc logs,
