TCP channel suddenly disconnected causing writer deadlock

[wangzm-R]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

When a subscriber TCP channel is suddenly disconnected, it does not block the normal release data of the publisher;

Current behavior

If a publisher and two subscribers are on unused hardware, and a subscriber's machine suddenly power off, the publisher will be blocked after 1min; once the subscriber's device is activated again, the publisher will return to normal;（use static ip）

Steps to reproduce

use publisher and subscriber;

Hi @wangzm-R,
Thank you for using Fast DDS.

In Fast DDS 2.14.1 there are many improvements related to TCP and this issue might be fixed in the latest version. Can you try and let us know if it's fixed?
