Unable to terminate QCoreApplication

[yagabey]

Hello,
I am trying to connect to a host in my core application. If socket can connect to the host; no problem...But if it cannot resolve the hostname, the application stucks there. The application doesn't crash; but just refuses to exit, after that point...

I tried QCoreApplication::exit() and standart c library exit() functions, none could terminate the program. Is there any way to exit the program, no matter how?

that is the stubborn connecttohost function:

d->socket->connectToHost( d->pop3_server , d->port );

d->socket->connectToHost( d->pop3_server , d->port );

I tried (not good but, need it.. ):

QTimer::singleShot(20000, this, SLOT(exitnow()));

QTimer::singleShot(20000, this, SLOT(exitnow()));

my slot:

void Pop3::exitnow()
{
        QCoreApplicaition::exit(0);
}

void Pop3::exitnow()
{
        QCoreApplicaition::exit(0);
}

also tried:

void Pop3::exitnow()
{
        exit(0);
}

void Pop3::exitnow()
{
        exit(0);
}

I debugged the application and saw that the exitnow() slot is called;but the application doesn't terminate.
