WS API client does not emit events #9142

Closed sameersubudhi closed 7 months ago

sameersubudhi commented 7 months ago

Expected behavior

The WS API client when connected should always emit the chain_* events.

Actual behavior

When running Lisk Service against Lisk Core (or any other application) for a prolonged duration (at least a couple of days) using the WS API client stops emitting any of the chain_* events resulting in Lisk Service being stuck in a state of limbo even while the chain continues to progress.

Steps to reproduce

Run Lisk Service against Lisk Core v4.0.0 on testnet for a few days

Which version(s) does this affect? (Environment, OS, etc...)

v6.0.0

Sometimes we get following timeout error when trying to automatically reinstantiate the WS API client.

The WS API client has been running against my testnet nodes for several days and it has been showing chain_* events correctly.

According to @sameersubudhi, the reported behavior could have been solved with correct re-instantiation of API client by Lisk Service in https://github.com/LiskHQ/lisk-service/issues/1920.

I will close this issue now. If the problem re-appears, please feel free to re-open it.
