Assertion failed: "non-unique {comment_driven_log}.cid: 55".

I get this error report consistently on a page that contains a comment driven comment.

"Assertion failed: "non-unique {comment_driven_log}.cid: 55". Please report this bug."

A comment was added and a node property of type date was changed. The node is part of a group post(Organic Groups)

Did check for similar issues , couldn't find any. Please let me know if any more details are required and let me know how to get those details :)
