librdkafka消费一段时间后报错REQTMOUT...Timed out FetchRequest in flight

kafka版本2.6.0

kafka正常运行，跨网域分布式部署，消费者远程消费broker消息，正常消费一段时间后报错：

%5|1677555150.963|REQTMOUT|rdkafka#consumer-2| [thrd:ssl://IP:9093/bootstrap]: ssl://IP:9093/0: Timed out FetchRequest in flight (after 61305ms, timeout #0)

大概每60000ms报一次（1min），session.timeout.ms, heartbeat.interval.., request.timeout.ms等均采用的默认配置。

消费断断续续，时好时坏。
