Java 堆空间 - 内存不足错误 - 带有 SASL_SSL 的 Kafka Broker

当我在带有 PLAIN_TEXT 端口 9092 的 Kafka 代理中使用以下“/usr/bin/kafka-delete-records”命令时，该命令工作正常，但是当我使用 SASL_SSL 端口 9094 时，该命令会引发以下错误。有人知道将 Kafka 代理端口 9094 与 SASL_SSL 一起使用的解决方案吗？

$ssh **** ****@<IP address> /usr/bin/kafka-delete-records --bootstrap-server localhost:9094 --offset-json-file /kafka/records.json`
