HTTP GOAWAY frame from worker under high load
I am connecting to a worker via HTTP2. When I’m sending lots of events via the same connection (but not more than 50-100 events per second) I keep getting a GOAWAY frame after a while.
I’d love to know the reason for this so I can decide how to handle it.
- just maintenance on your side? (but it feels to me like its load connected)
- some DDoS protection? (but 100 events per second seems low)
- routinely asking to recycle the connection after x events?
I’d also like to know whether you’re passing additional information like error code, last stream Id etc in the frame. If so we’d need to move to a lower level http client to take advantage of this information.
Thanks!

Behavior of blockConcurrencyWhile when used outside of durable object constructor
The examples for usage always show this being used in the constructor of a durable object to prevent concurrent execution of requests while initialization is not yet done. Is this the only way this should be used?
In our project we're using blockConcurrencyWhile in one of many routes handled by the fetch method. What is the expected behaviour in this case? How should requests or alarms that have already kicked of before calling blockConcurrencyWhile for another request behave? Will they be stopped or could they be executing concurrently?
