<p>Hi <a href="https://github.com/kelnos" class="user-mention">@kelnos</a> , your backtrace points to the lock for protecting the write operations on a TCP connection. This means you have a connection with a very very slow (and possible blocking) writing. <br>
I would suggest to switch to async writing for TCP:<br>

or to stay in blocking mode but to reduce the write timeout:<br>
