Log noise to do with websockets

[dboreham]

We see constant log output like this, under normal operating conditions:

Sep 27 13:37:44 vaasl-cerc-1 chibaclonkd[418747]: 1:37PM ERR Failed to read request err="websocket: close 1006 (abnormal closure): unexpected EOF" module=rpc-server protocol=websocket remote={"IP":"127.0.0.1","Port":39564,"Zone":""}
Sep 27 13:37:44 vaasl-cerc-1 chibaclonkd[418747]: 1:37PM ERR not stopping client; it is already stopped client=wsConnection module=rpc-server protocol=websocket remote={"IP":"127.0.0.1","Port":39564,"Zone":""}
Sep 27 13:37:44 vaasl-cerc-1 chibaclonkd[418747]: 1:37PM ERR error while stopping connection error="client is not running" module=rpc-server protocol=websocket

This output is not useful and clutters the log making it hard to determine if the service is operating correctly.

Task is to stop this log output from appearing, one way or another.

Quick search of the laconicd source code shows that these messages are not coming from our code. Probably originate in a dependency. Checking...

Found it here:

https://github.com/tendermint/tendermint/blob/main/rpc/jsonrpc/server/ws_handler.go#L97

Code where the messages are generated:

https://github.com/tendermint/tendermint/blob/main/rpc/jsonrpc/server/ws_handler.go#L327
https://github.com/tendermint/tendermint/blob/main/rpc/jsonrpc/server/ws_handler.go#L97

(Can't find the code for "not stopping client; it is already stopped" yet)

Possibly here? https://github.com/tendermint/tendermint/blob/main/libs/service/service.go#L174

Resolved by rebasing to older CosmosSDK

Reports are the message persists in the latest release, re-opening.
