Problem conclusion

Temporary fix

Comments

• In case the response buffer size is exceeded, a trace is
  issued to provide information about the use of that part of
  the storage and facilitate the analysis.
  The processing is not stopped. Where possible the code tries
  a recovery by means of a reallocation attempt.
