We have 4 consumers , each one for different topic.

3 works fine but 4th one gives this error and as offset is not commited, if 
consumer is started , it begins reading from starting.

Route config is as below:

<from
                           
uri="kafka:{{financial.kafka.host}}?topic={{financial.order.kafka.topic}}&amp;groupId=ilCamelOrderSub&amp;autoOffsetReset=earliest&amp;securityProtocol=SSL&amp;serializerClass=org.apache.kafka.common.serialization.StringSerializer&amp;sslTruststoreLocation={{kafka.truststorelocation}}&amp;sslTruststorePassword={{kafka.truststorepassword}}&amp;sslKeystoreLocation={{kafka.keystorelocation}}&amp;sslKeystorePassword={{kafka.keystorepassword}}&amp;consumersCount={{kafka.order.consumersCount}}"
 />

Please could someone help us here if they have faced same issue.
