EMP-Connector Missing to Consume Events While still being Subscribed and Long Polling

[techy-spongebob]

EMP Connector is missing to consume events while still being subscribed and long polling the salesforce server. We found two scenarios when this happened.

• Scenario 1 - The event was produced exactly at the same instance when long polling ended. When client connected back for next long polling, it did not receive the event.
• Scenario 2 - At times, even when the event is produced when the client is in middle of long polling, server did not send any event to the client. Client returned with EOF Exception from the server.

We worked with salesforce on this and they confirmed that events are delivered to the clientIds which we claimed that missed those events.

Any insights on why client is missing these events.?

What happens if you try to replay from the last known offset ?
