Order of consumed messages in the same partition.

Hi all,
I would like to know if there is any possibility to consume one message for
a given topic and partition, using the high-level consumer, that has the
offset lower than the last consumed offset from the same topic and
partition couple.

It seems that I am experiencing this problem in mine application, and
wondering if it a possibility, or is a bug in our codebase.

Thanks for any helps.
