KafkaException: Size of FileMessageSet has been truncated during write

[Andrey Yegorov]

I've noticed a few exceptions in the logs like the one below, does it
indicate data loss? should I worry about this?
What is the possible reason for this to happen?
I am using kafka 0.8.1.1

ERROR Closing socket for /xx.xxx.xxx.xxx because of error
(kafka.network.Processor)
