DDS (IDL)

I try to communicate with different module using DDS (IDL) in same machine. the data size is big.
When I try to publish my data I have this error:

REDAFastBufferPool_growEmptyPoolEA: !allocate buffer of 39454018304 bytes
REDAFastBufferPool_newWithNotification:!create fast buffer pool buffers
PRESTypePluginDefaultEndpointData_createWriterPool:!create writer buffer pool
WriterHistorySessionManager_new:!create newAllocator
WriterHistoryMemoryPlugin_createHistory:!create sessionManager
PRESWriterHistoryDriver_new:!create _whHnd
PRESPsService_enableLocalEndpointWithCursor:!create WriterHistoryDriver
PRESPsService_enableLocalEndpoint:!enable local endpoint
DDSDataWriter_impl::createI:ERROR: Failed to auto-enable entity
! Unable to create DDS data writer

After that I also do two things according to blog

First 1 in USER_QOS_PROFILE.xml : add

<participant_qos>
                    <discovery>
                              <initial_peers>
                                    <!-- Insert the addresses here of the machines you want to contact -->
                                    <element>127.0.0.1</element>
                                    <!-- <element>192.168.1.2</element>-->
                              </initial_peers>
                         </discovery>

</participant_qos>

2 nd in  /etc/sysctl.conf : add

Although I have same Error.
