> Project: Camel
> Issue Type: Bug

> We're occasionally seeing the following Mina exception on our production environment: "IllegalStateException: doDecode() can't return true when buffer is not consumed." (full stack trace below)
> I haven't been able to reproduce the issue, and I don't fully understand the problem, but I think it's caused by duplicate messages (or specifically duplicate end byte markers) in the Mina IoBuffer that is read by Camel's HL7MLLPDecoder.
> Full stack trace (with truncated hex dump):
> org.apache.camel.CamelExchangeException: Error occurred in ResponseHandler. Exchange[ID-prdvpn01-zd-messaging-37296-1475153396916-0-335909].
