ISymbolOrderBook Stops Receiving Updates After Random Intervals

[Amitabitbul]

Description
After a random period of time, the IFactoryOrderBook service stops receiving updates. This issue seems to occur intermittently and does not follow a predictable pattern. It is critical for the proper functioning of our application that the IFactoryOrderBook service receives updates continuously without interruption.

Steps to Reproduce
Start the application.
Ensure that the IOrderBookFactory (IOKXOrderBookFactory, and IBybitOrderBookFactory) service is injected and ISymbolOrderBook instance has been created from the Factory.
Monitor the ISymbolOrderBook updates over a period of time.
Observe that after a random interval, the service stops receiving updates.
Expected Behavior
The IFactoryOrderBook service should continuously receive updates without any interruptions.

Actual Behavior
The ISymbolOrderBook service stops receiving updates after a random period of time.

there are no error logs or exceptions, it just does not raise the events anymore

I'm trying to listen to the Symbol Orderbook in Bybit and OKX.

[JKorf]

Hi, does this happen for both Bybit and OKX? Or just OKX?

[Amitabitbul]

For both, and for mexc. I tried them all, and its weird.

[JKorf]

I'll investigate. Any information that might help to reproduce? How many books are you subscribing, do you have other subscriptions running, after which time does it most often stop updating? etc

[Amitabitbul]

I attempted to listen to the Solana/USDT trading pairs on OKX and Bybit, using various depth settings (5, 50, and the default). While the updates initially streamed correctly, they eventually stopped printing, and the updates handler ceased firing. Additionally, there were no logs or exceptions indicating an issue; it simply halted.

It happened after 16 mins.

[JKorf]

These warnings are not directly an issue. There might be an interruption in the internet connection, or the server might disconnect. That is to be expected. The library should automatically reconnect and the book should be resynced after.

[Amitabitbul]

Sure, but it didn't, it stopped working.
It never synced again and there is not more logs, those logs written 16mins after running the code.

There is no internet interruption.

I tried to run it in wsl and windows as well.

Same behavior.

[JKorf]

I haven't been able to reproduce this. Is it possible to run with a more verbose log level? Seems only warnings are logged. Or alternatively, could you create a minimal reproduction project?

[Amitabitbul]

Sure, I will share a sample project with your gh

[Amitabitbul]

@JKorf DemoProject shared with you, many thanks.

[JKorf]

Hi, I checked out your repo. The initial problem I'm having is that the console logging can't keep up with the data. So it just seems to hang somewhere at some point.
I made some changes in the jkorf branch, can you check if you still have issues using it like that?

[Amitabitbul]

@JKorf can you share a link? I'm not finding it

[JKorf]

Sure, https://github.com/Amitabitbul/DemoProject/tree/jkorf

[Amitabitbul]

@JKorf I'm not sure it going to work.

Try to place a BP inside the callback, and you'll see it's not triggered when the prints stops.

[JKorf]

The version in my branch has been running for 3 hours now. It's continuously printed the top 5 levels of the order book, and a breakpoint in the best offer change callback still triggers. Have you run the version in my branch?
