Data Loss Issue with DDS Statistics Module with Multiple Publishers and Subscribers

[Jackie2chen]

I am experiencing a data loss issue while using the ddsstatistic module when working with multiple publishers and subscribers. Despite following the QoS configuration recommendations from the troubleshooting guide here, the problem persists.

Specifically, I have noticed that the issue is more pronounced when the number of topics exceeds 20. While the QoS adjustments have shown some improvement with fewer topics (around two or three), latency data continues to be lost as the number of topics increases.

Details:

I have implemented the recommended QoS settings.
Data loss is observed with latency metrics.
The problem becomes significant with a higher number of topics (around 20).
Questions:

Are there additional configurations or adjustments that can be made to handle a larger number of topics effectively?
Could there be any specific limitations or considerations related to data loss when scaling up the number of topics?
Any guidance or suggestions to resolve this issue would be greatly appreciated.

Thank you!
