[Quickfix-developers] Cannot reconnect after ungraceful disconnect

[John D. <joh...@ch...>]

Hi,

We are having issues re-establishing QuickFIX sessions after our initiator
disconnects ungracefully. We have traced through the code, and our problem
seems to be this loop inside ThreadedSocketConnection::setSession():

// see if the session frees up within 5 seconds
for ( int i = 1; i <= 5; ++i )
{
    m_pSession = Session::registerSession( sessionID );
    if ( m_pSession ) break;
    process_sleep( 1 );
}

Question 1: What is this loop doing? Who is going to free the session within
5 seconds?

As I step through Session::resgisterSession(), the problem seems to be here:

if ( isSessionRegistered( sessionID ) ) return 0;

isSessionRegistered() always returns true, so the session is never
re-established.

Can anyone help me understand what is going on here? When should
isSessionRegistered() return false? After a session has been physically
disconnected? At some other time?

Thanks in advance for any help or advice.

John
