If it is not enough, you can try to reduce it further (e.g. 1MB) and you can also reduce the number of partitions withoffsets.topic.num.partitions. It is 50 by default. 5 may be enough for your tests. |

Kafka 4.0 currently runs out of memory when a high max message size is used, lowering this allows us to test against Kafka 4.0 in CI#1360 (comment)
For consistency I have done this everywhere for all Kafka versions we test against. It was probably a mistake to make it so large from the start
