Channel Callback Client recieved ChannelDownReconnecting Message
Hello :)
I saw the error message like below a few hours ago.
After Nasdaq market opened, the message occured.
What is ChannelDownReconnecting?
loggerMsg ClientName: ChannelCallbackClient Severity: Warning Text: Received ChannelDownReconnecting event on channel DATA_CHANNEL_1 RsslReactor ===== RsslChannel ===== Error Id 0 Internal sysError 0 Error Location null Error text Connection reset loggerMsgEnd
Hi @goodsgjung
Do you have a large watchlist of instruments and/or are you performing considerable processing in the main onRefesh or onUpdate callbacks? If so, you could be starving the API thread (that calls the onRefresh and onUpdate callbacks) - which could mean the API cannot read all the data from the server in a timely manner and the server disconnects you.
The above may not be the case - but I mention this because it is a possibility.
A few posts related to 'slow consumer'
Are you connecting to an internal ADS server or using our RTO cloud-based service?
If internal ADS, speak to your internal MarketData team who can check the logs for any disconnects and the reason.
IF RTO, then please raise a ticket at My.Refinitiv for the Real-Time Optimised with details of your machineID and disconnect times - they may be able to check their logs also.
Hello @goodsgjung ,
This likely means that channel was down and EMA API was working to recover it.
You may wish to review the discussion of "Single Open" concept in EMA RDM Guide. By default, an EMA consumer is utilizing "Single Open" and upon connection loss, EMA API attempts to recover the channel without action required from app developer. Once the channel is re-established, EMA attempts to re-subscribe any existent item streams. It is possible to modify this behavior, via attributes passed, please find the details in RDM guide.
