Repeatedly trigger service discovery procedure will lead to memory leak

[MengDes]

Is there an already existing issue for this?

• [X] I have searched the existing issues

Expected behavior

two process A and B communication use dds ，and C is one participants in dds networks ， proc C 's memory should be fixed

Current behavior

Repeatedl restart A or B, and C will start discovery procdure, and memory usage will sustained growth, use varlgrind we found many memory possibly lost relevant to service discovery, such as eprosima::fastrtps::rtps::PDP::addReaderProxyData

Steps to reproduce

restart A or B

Fast DDS version/commit

fast dds 2.1.4

Platform/Architecture

Ubuntu Focal 20.04 amd64

Transport layer
