Reducer task gets killed on it's own

I am finding that with reasonably big files, some of the reducers get killed(with the status KILLED_UNCLEAN), and then another attempt is made, which completes successfully. I have no idea what is causing this. I read in some other forums that this could happen if Speculative Execution is turned on. I turned it off but still the problem persisted.
This problem does not happen if the file is small(say few MB). I would really appreciate any thoughts on fixing this.
