[zeromq-dev] Perl bindings ZeroMQ block publishing messages to Mojolicous over WebSocket

I am trying to write a simple Perl code which subscribe messages from ZeroMQ and publish them over WebSocket using Mojolicious.
As soon as I subscribe to zeromq for receiving messages, the websocket sent part stops working.
If I try to dump the $self->tx, I see the messages and the correct client information, but no data is being sent.

Please find below a sample code snippet for this,


use strict;
use warnings;
use Data::Dumper;
use Mojolicious::Lite;
use ZMQ::LibZMQ3;
use ZMQ::Constants qw(:all);

websocket '/paper' => sub {
                my $self = shift;

                my $ctxt = zmq_init;
                my $socket = zmq_socket( $ctxt, ZMQ_SUB );
                zmq_connect( $socket, "tcp://manu.rsi.com:7000" );

                $self->app->log->debug('WebSocket connected.');

                $self->send('WebSocket connected.');

                while(my $msg = zmq_recvmsg( $socket )){
                                $self->send("Received a message data");




Please let me know if I am missing something or is there a different way to achieve this.
I am trying a simple glue code, which gets Messages over ZeroMQ and send over Mojo WebSocket.
