Memory leak in TCPChannelResource

[ulongcha]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

When TCPClient left domain, its tcpchannel in TCPServer should be removed.

Current behavior

When TCPClient match TCPServer, TCPServer's memory increase and will not decrease.

Use valgrind --tool=massif to generate a memory report also find increase memory in TCPChannelResource.

Steps to reproduce

Run DDSHelloWorldTCP demo with Server and Client, frequent start and stop Client.

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.

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.
