因RPC限速导致sequence-sender异常退出

相关代码

type RetryHandler struct {
    RetryAfterErrorPeriod      time.Duration
    MaxRetryAttemptsAfterError int
}

func (h *RetryHandler) Handle(funcName string, attempts int) {
    if h.MaxRetryAttemptsAfterError > -1 && attempts >= h.MaxRetryAttemptsAfterError {
        log.Fatalf(
            "%s failed too many times (%d)",
            funcName, h.MaxRetryAttemptsAfterError,
        )
    }
    time.Sleep(h.RetryAfterErrorPeriod)
}

解决

在sequence-sender 配置->L1InfoTreeSync下增加两个配置

• MaxRetryAttemptsAfterError 总共重试多少次后，异常退出，可以设置一个较大值
• RetryAfterErrorPeriod：每次重试的间隔时间
