因RPC限速导致sequence-sender异常退出

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
