runtime error: invalid memory address or nil pointer dereference

[HQ1363]

Description

I have multiple producers who send messages to different kafka cluster instances, and their topic names are the same. After the program runs for a period of time, it will suddenly panic.

Versions

Sarama	Kafka	Go
1.38.1	2.8.2.7	go1.21.3

Configuration

c := sarama.NewConfig()
c.Producer.RequiredAcks = sarama.WaitForAll
c.Producer.Return.Successes = true
c.Producer.Return.Errors = true  
c.Producer.Flush.Messages = 10 
c.Producer.Flush.Frequency = 500 * time.Millisecond

It’s unclear what the problem is, but a number of fixes have happened since 1.38.1. Have you tried upgrading to v1.43.3 already?
