I think this may be somewhat related to #966

I get TIME-WAIT instead of CLOSE_WAIT . Any body has idea on wait_for_tcp_negotiation option in tcp transport descriptor

@MiguelCompany Would upgrading to Fastdds 2.3.0 solve this issue ?

@RamcharanPalnati,

This issue might have been solved by #2470 which has been backported to currently supported Fast DDS releases. I am going to close this issue as Fast DDS (formerly known as FastRTPS) 1.9.x is no longer supported. Feel free to reopen if the issue is still happening in newest versions of Fast DDS.
