Error description

• Starting with server version 8.1.22, many messages like the ones
  below may reported in the dsmffdc.log:
  
  .....[ FFDC_GENERAL_SERVER_ERROR ]:
  [41772](output.c:5444)(SESSION: 21580) Buffer queue is full for
  Stream 0x1553b42ee610, recvType 0. Data discarded. Max Buffsize
  is 32000, Current buffersize is 32064.
  
  .....[ FFDC_GENERAL_SERVER_ERROR ]:
  [41772](output.c:5444)(SESSION: 21580) Buffer queue is full for
  Stream 0x1553b42ee610, recvType 0. Data discarded. Max Buffsize
  is 32000, Current buffersize is 32064.
  The number of these FFDC_GENERAL_SERVER_ERROR message matched
  the number of total numbers of these messages ANR8592I,
  ANR0839I, ANR0403I, ANR0511I, ANR0838I.
  
  While the real buffer size (32064) of these messages is greater
  than the default buffer (32000), the server logs Buffer queue
  full messages in the dsmffdc.log.
  The server should not log these messages to in dsmffdc.log
  because there was no error.
