TREP: Unexpected "Output threshold breached for <user>...."

philippe.mesmeur

Hi,

I developed a JAVA application based on Refinitiv Realtime SDK, that is consuming RICs on TREP.

Today, one of my customer reporting an issue that he was able to observe many time during the night:

• my application is disconnected from TREP
• ADS logs shows errors such as Output threshold breached for XXX" at position "12.23.45.78/abcdef" on host "thehost" and port number "12345" using application "256"

According to what I can read, it seems that my application does not consum RICs fast enough. However:

• at this time, the activity is not so huge (client think "only" around 1000 RICs per seconds)
• but during the day, the application is able to work easily with an activity (according to the client) around 4000 RICs per seconds

So there is apparently no reason why my application would not be able to consum the stream

According to your knowledge and your experience, what could be the reason of the error my client is having?

Is it possible to tune the "EmaConfig.xml" (or my java code) in order to avoid this error (or at least to reduce the risk it occurs)

Thank you

Regards,

Philippe

Thank you for reaching out to us.

Typically, this error indicates that the output buffers used by this connection breached. It could be a slow consumer or network issue. You may increase the number of output buffers via the ADS configurations. The current settings may be too low.
