"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

Hi,

While running iqconnect under wine, I see that the internal _IQIF_SBL1 socket from a Derivative stream hangs causing subscribed bars to stop and for the _IQIF_SBL1 socket to start reporting queued data. This typically occurs during heavy market activity around open. However, I have seen it happen randomly through the day. I'm subscribing to 12 liquid equities and 23 liquid futures contracts. If the KBQueue reaches 10MB, I close all connected and open new ones. All sockets close except for the _IQIF_SBL1_***. These just keep piling up queued data until I restart iqconnect or eventually run out of memory. I'm running this in a docker container. I'm happy to share the Dockerfile if that helps.

I've had this issue for years now. My solution was to just kill the iqconnect process and restart it. This has become an issue for me and I can no longer afford to have interruptions in iqconnect.

In this first section of logs, you can see that the _IQIF_SBL1_*** connection stops delivering data(sent). It just piles up (kbqueued) I see no logged errors prior to this. I'm not sure what the level of logging is set to. If you can tell that debugging is not set, please let me know how to set this in a registry in 6.2 (64bit). I don't have easy access to the Diagnostics app

I'm using the dotnet client so graciously provided here https://github.com/mathpaquette/IQFeed.CSharpApiClient

In this client, I see that the sockets are not explicitly disconnected, they are just disposed. It seems that this results in a quick release of the sockets on the iqconnect side in normal circumstances. I believe this causes the socket to be held onto by iqconnect when it enters this queued state. In the queued state, where the IQ derivative process in iqconnect no longer reads from the internal L1 socket, will hold onto this internal socket even though I am no longer connected to the derivative port. Data just piles up until it crashes when there is no more memory left.

On a positive note, if I explicitly disconnect from the derivative socket before disposing, iqconnect will eventually (30-60 seconds later) release the internal socket to L1. I have been able to reconnect to only the derivative socket without restarting iqconnect. All my sockets that are connected to L1 directly work fine through this problem.

Any insight as to why the derivative process would stop reading from its internal L1 socket would be helpful. I've had to write a bunch of code to circumvent this issue.

I will say, I don't believe this is an issue on Windows, only while running with wine.

The above approach to closing the socket is not working, iqconnect (or wine) is holding the internal iqconnect 5009 port open even after I disconnect my app.

This is causing me to repeatedly have to restart iqconnect (many times per week). I am currently developing an app to generate my own bars from level 1 data. Once I have this running I will stop connecting to the derivative port in production.

If I can create a docker file that reproduces this issue, could IQ support run this and see if it is reproducible on your end? I only see a problem under heavy market volume, so you might need to run for a few days before the internal port hangs.

Yes, please do, and send it to me at the main IQFeed support email address.
