The voluntary exit pruning logic seems a bit strange and suboptimal:

    pub fn prune_voluntary_exits(&self, finalized_state: &BeaconState<T>) {
        prune_validator_hash_map(
            &mut self.voluntary_exits.write(),
            |validator| validator.is_exited_at(finalized_state.current_epoch()),
            finalized_state,
        );
    }

Could it be more effi

In winston logger, logger.profile, if level is not explicitly set, set to verbose.

Edit:
Log profiling logs to verbose, not info.

recently CI failed many times testing cluster because of port already used, which can be very annoying.
