Consumer stop messages consuming from specific topic after some time of running - node.js

Question

Environment Information
docker image based on node:12.13.1-alpine
Node Version : 12.13.1
node-rdkafka version : latest
The below code snippet is working fine. But sometimes it's stopping reading messages from specific Kafka's partition (we are having about 20 topics (5 partitions each one) with same pattern). We are not getting any errors. After service restart and rebalance consuming continue as usual. Which tuning should be done to manage those stuck partitions?
Throughput is low, it's about 150 messages for all topics per minute, each message is small JSON with some details (~500kb). We are running with 10 pods for specific service.
import { ConsumerStream, createReadStream } from 'node-rdkafka';
const kafkaConsumer = createConsumerStream(shutdown, config.kafka.topics);
kafkaConsumer.on('data', async (rawMessage) => {
const {
topic, partition, offset, value
} = rawMessage;
try {
await processKafkaMessage(rawMessage);
kafkaConsumer.consumer.commit({
topic: topic,
partition: partition,
offset: offset + 1
});
} catch (err) {
logger.error('Failed to process inbound kafka message');
}
});
