Using v1.2.0 of rdkafka appears to disconnect from the server at five minute intervals

[Super-long]

rdkafka version is v1.2.0

configuration is：
enable.partition.eof false
auto.commit false
max.poll.interval.ms 1200000

I'm using subscribe instead of actively selecting partitions, and after registering reblance_cb I noticed frequent Assigned and Revoked,

But in the meantime I'm always calling consume and not call consume->close, but it still triggers Disconnected.
I'd like to know if it's the configuration or the version, and how I can fix this tricky issue？

The reblance message reported on the server side is：reason: removing member rdkafka/x on LeaveGroup) (kafka.coordinator.group.GroupCoordinator)

I can provide more context
