Transaction commit (0x4cc61b15) redelivered(true) for (MessageId: ID:xx))

Issue

I get thousands of the following log lines in our log. How can I troubleshoot ?

2015-02-05 22:29:46,559 | INFO  | a.message.queue] | TransactionErrorHandler          | ring.spi.TransactionErrorHandler  261 | 165 - org.apache.camel.camel-core - 2.12.0.redhat-610379 | Transaction commit (0x4cc61b15) redelivered(true) for (MessageId: ID:amb46730app005.managed.cln-33443-1423124533819-5:1:7:1:39604 on ExchangeId: ID-amb46730app005-managed-cln-57053-1423124535348-1-788604))

and from the broker side I see:
