Hi,

Hi,

I believe your issue is related to your type. Do you have any unbounded sequences or strings in your XML type definition?
If so, you have two optoins:
- Give the unbounded types a bound (i.e., if you know that the string will never be longer than 1KiB, bound it to that).
- Set the following QoS in your XML
 

<datawriter_qos>
  <property>
    <value>
      <element>
        <name>dds.data_writer.history.memory_manager.fast_pool.pool_buffer_max_size</name>
        <value>4096</value>
      </element
     </value
   </property

 </datawriter_qos>
Note that in the above QoS snippet, i am setting the max_size to 4096, this is just an example, you will need to decide what you want the max size to be.
