Error 4040 Draining connection

Technical Issue Reporting
#1

I’m currently hitting this exception after some time while using Speedy Nodes:

websockets.exceptions.ConnectionClosedError: code = 4040 (private use), reason = Draining connection

#2

Hi,
What was the particular speedy node chain, were you able to reconnect successfully after that, after how much time usually it happens, how often it happens?

#3

Hi,

I’m using the BSC websocket speedy node, it is almost guaranteed to happen after between 15-30 minutes.

Hi @eXPerience

What type of data do you fetch?

I think you’re just hitting the limit ~ 3600 reqs/min.

#5

Hi, I dont think i’m even close to 3600reqs/min…

I’m fetching transaction data of my contract.
Pseudocode of my program is as below.

while True:
  logs = w3.eth.get_logs({
    'fromBlock' : last,
    'toBlock': latest,
    'topics': [myfunction, None, contract_address]
  })

  # do stuff

  last = w3.eth.block_number # RPC
  sleep(3)     # 3 seconds
#6

@eXPerience send me your node address in DM

#7

I don’t see your full code. But one of the possible reasons may be that there is a large interval between receiving information. And the websocket automatically closes the connection due to inactivity

#8

where do I click to send DM?
