Hi ulongcha, thanks for using Fast DDS.

This issue should be solved in Fast DDS 2.14.1, so you can try to upgrade to the new version. Let us know if the problem is solved.

Hi @elianalf I upgrade Fast DDS to 2.14.1, memory leak problem seems still exsist. Memory releated to TCP part still increases. image When I config TLS on TCP, the asio_ssl part also has memory leak. Maybe TCPChannel's resource not release correctly when Participant leave domain.
