file_corruption error on executing View

Hi
We have the latest version of couchbase server running on ubuntu 12 as a three node cluster.
We have a bucket with approximately 5 million records storing user session data.

Created a simple view on this bucket and put it into production.

On executing the view, we get some results along with the following error

"errors":[
{"from":"http://node3ip:8092/_view_merge/?group=true&stale=false&limit=100","reason":"{file_corruption,<<\"file corruption\">>}"}
]

The error always comes for node3 and occurs for all views. I have tried with two views.
How do we go about fixing this issue?
