QTcp socket multi threaded application

[suhas.ga]

I have created a multithreaded qtcpserver which creates a new thread whenever a new incomming connection occurs . But when i get the data readyread signal is sometimes getting emitted and sometimes it is not getting emitted...

Does anyone knows anything about this issue.??

How do you know it is not emitted? How did you connect to the new threads?
Some code might give some insights.

I have kept a debug print in the readyread signal. When I am using in ubuntu it is sometimes printing and sometime not printing. In windows it is working .

This is the way I am creating the thread

NewConnection *newCon = new NewConnection(sock->socketDescriptor(),PresentTablesCount);
qDebug()<<sock->socketDescriptor();
connect(newCon,SIGNAL(finished()),newCon,SLOT(deleteLater()));
newCon->start();

in thread run i am using in this way

socket = new QTcpSocket();
if(!socket->setSocketDescriptor(this->socketDescriptor))
{
qDebug()<<"error in setting sock desc";
return;
}
connect(socket, SIGNAL(readyRead()), this, SLOT(OnReadyRead()), Qt::DirectConnection);
connect(socket, SIGNAL(disconnected()), this, SLOT(OnDisconnected()));
exec();

ReadyRead slot

qDebug()<<"in ready read";
QByteArray = socket->readAll();
