Hi @Wyatt-Bennett, Apologies for the delayed response. Could you please check if this issue persists in the more recent versions, such as 2.14 or 3.x? Thank you! |

Is there an already existing issue for this?
Expected behavior
The expected behavior is that the application works regardless of the number of parameters of a given topic.
If the topic has up to 1000 parameters it works correctly.
Current behavior
When the topic has more than 1000 parameters, the publisher and the subscriber make the connection but the publisher's DataWriter does not send any parameters through DDS. in this scenario, if you try to open Fast-DDS-spy after installing it, the publisher automatically closes.
If the topic has less than 1000 parameters, the application works correctly.
Steps to reproduce
After installing FastDDS-2.13.1 on Windows 10, starting from any sample application, e.g. DynamicHelloWorldExample, modify the publisher, the subscriber and the .xml files to add 1100 parameters in the topic.
Build the application with visual studio 2019 and run it. It will check that the publisher does not send the topic to the subscriber.
Then modify the files so that the topic has 900 parameters. In this case, the publisher correctly sends the topic to the subscriber.
