I'll continue investigating the issue. Any insights are welcome.
What is the version of your websockets? I'm using 7.0; not sure if newer or older, but yours seems incompatible
Was using websockets 8.1, went back to 7.0 Unfortunately crashed again.
$ pip3 show websockets
Name: websockets
Version: 7.0
Including the logs, maybe you see something interesting.

Both docker instances stop at the same block height with the same error. They have been running for months until this crash last week.
I've compacted the fist docker instance and run it, still crashes.
It seems the BSV block #622559/622560 has some weird txs that could crash the electrumX.
I will try the latest electrumX version to see if it makes any difference.
Yes that is the problem, you need to be on 1.14 for Genesis. I'm not sure what the txs are but you may have to rebuild the DB from scratch.
Sorry kyuupichan, but what randydu is refering to has nothing to do with the issue i posted in the first place. I am still experience the same behaviour, crashing every now and then, with websocket 8.1 & websocket 7.
@angelix the error shown: "AttributeError: 'WebSocketServerProtocol' object has no attribute 'transfer_data_task'" originates in the websocket package and refers to a problem within its data structures. I suspect your installation of the package is somehow corrupted.
https://github.com/aaugustin/websockets/blob/master/src/websockets/protocol.py#L278 is where it is defined, apparently
Downgraded to websockets v7, different exceptions are occurring. Don't know if a client message is doing this, but even that shouldn't bring down the server.

@kyuupichan We are still experience crashes almost every 1-2 hours. Is very difficult to debug or reproduce, but using the following artillery script was able to.
npm install -g artillery
vim test.yml # paste the content of the previous comment
artillery run test.yml
If you run it multiple times you can "bring" down a websocket electrumx server eg. BSV
I'm also having this issue, that "WebSocketServerProtocol" object has no attribute 'transfer_data_task'
This is my log:

It appears randomly too. Sometimes in the next 12 hours, sometimes after 3 days. I'm not using artillery or something like that. I'm just using plain Ubuntu 18.04
I'm also having a different issue by "code = 1006 (connection closed abnormally [internal]), no reason" (other error output)

This appears randomly too. I'm not quite sure if this issue is related with this topic. (But it has still something to do with websocket)
My other mirror ElectrumX (WebSocket) Server seems to be fine with very very low activity. (around 3-4 Users each day)
The error from above seems to appear from my main ElectrumX Server which has much more activity, around 500 Users each day. (Of course not all at once).
