Hello Sudarshan,
It appears you are using the v201101 ReportDefinitionService. Please correct me if I got it wrong. Please note this service is scheduled for sunset on 29 Feb 2012. You should migrate to AdHoc reporting as soon as possible. AdHoc reporting is much faster and I expect no such errors for it in your configuration.
