I've been running fine for the past year or so with no problems what-so-ever, but after the new year, I must reboot my server every morning in order to properly connect to IQFeed. My application is written in Java and I use IQFeed 4.9.0.3 on a Windows Server 2008 running 68 bit.

One (possibly important) point is that my application connects to IQFeed in the morning and typically disconnects in the evening around 9:00PM. However, the iqconnect.exe will sometimes stay up all night (not always, but sometimes).

Anyway, the technique the I use to connect is as follows (with autologin information provided in the IQFeed dialog box):

-----------------------------------------------------------------------------------------------------
Runtime.getRuntime().exec ("iqconnect.exe -product PRODUCT_NAME -version 1.0");
Thread.sleep (5000);

Socket sockAdmin = new Socket(InetAddress.getByName("localhost"), 9300);
BufferedReader bufreadAdmin = new BufferedReader (new
InputStreamReader (sockAdmin.getInputStream()));
BufferedWriter bufwriteAdmin = new BufferedWriter (new
OutputStreamWriter (sockAdmin.getOutputStream()));
String strAdminLine = "";
// loop while we are still connected to the admin port or until we are connected
while (((strAdminLine = bufreadAdmin.readLine()) != null) && !bConnected)
{
System.out.println (strAdminLine);
if (strAdminLine.indexOf (",Connected,") > -1)
{
System.out.println ("IQConnect is connected to the server.");
bConnected = true;
}
else if (strAdminLine.indexOf (",Not Connected,") > -1)
{
System.out.println ("IQConnect is Not Connected.\r\nSending connect command.");
bufwriteAdmin.write ("S,CONNECT\r\n");
bufwriteAdmin.flush ();
}
}

// cleanup admin port connection
sockAdmin.shutdownOutput();
sockAdmin.shutdownInput();
sockAdmin.close();
bufreadAdmin.close();
bufwriteAdmin.close();
iqFeedStarted = true;

Thanks,

Jason

Jason, what would be more important in this scenario would be how you are disconnecting from the feed since it seems that IQConnect is remaining running after your app closes.

When you shutdown your app, does the connection manager still show in your system tray/notification area? If so, what does the Clients Connected show? If not, does iqconnect.exe still show up in the list of running processes?

If the Clients Connected shows zero, what is the value of the following registry key?
HKEY_CURRENT_USER\Software\DTN\IQFeed\Startup\ShutdownDelayLastClient

Lastly, what exactly happens when you try to connect again? Are you not able to connect to the Admin port or is there some other issue?

Steve,

I'll have to update the ticket tomorrow as I cannot reproduce it until the next morning.

Thanks,

Jason
