Exception in deleting Log segments

["Vanteru, Rammohan Reddy" <ra...@blackrock.com>]

Hello users,

We are using kafka 0.11 2 node kafka cluster which is running on Linux. Has any one faced below error while cleaning up old segments. Do I need to manually clean up old segments? Any info provided would be help full.
