Assert hit in round robin assignor

See original GitHub issue

via: @wwarby https://github.com/confluentinc/confluent-kafka-dotnet/issues/1366#issuecomment-668669487

I’ve just run into massive instability after upgrading some high throughput C# apps from v 1.4.4 to 1.5.0. In my case the error thrown is

dotnet: rdkafka_roundrobin_assignor.c:97: rd_kafka_roundrobin_assignor_assign_cb: Assertion `next < rd_list_cnt(&eligible_topic-> members)’ failed

… and results in an all out application crash. Rolled back to 1.4.4 and it solved the problem.

In my case, I’m consuming data from topics that already exist and I don’t have topic auto-creation enabled - I’m running multiple instances of the C# app, each instantiating a single consumer to join the consumer group.

@mhowlett will you pre-release v1.5.3-RC5 ? I’m looking for checking if my issues are gone after update.
