I'm invoking my chaincode via node-sdk by queueing the submissions via the async package. However, I very often get a error: [EventService]: EventService[org1-peer1] timed out after:3000. There's no additional information at the peer's log. The transaction is getting processed, though.
Here's the client log (GRPC_VERBOSITY=DEBUG, GRPC_TRACE=all):

Every idea is highly appreciated!
That error is generated when no events are received within a timeout window after connecting the event service to receive block events from peers. It's possible that this one peer is not responding but transactions can still flow as there are enough contactable peers for endorsement to be successful. If the logs confirm that all of your peers are communicating correctly and your transactions are all executing OK then probably this error is spurious and you can ignore it.
However, even if the error log is spurious, it would be nice if it wasn't there. It might be that an unsuccessful reconnect is being triggered due to ordering of operations within the Gateway.disconnect() process but I'm just guessing here. It might be worth raising a bug report in Jira against the Node SDK for further investigation:
