Netflow Analyzer Sudden Not Show Last Hour Application Data

Netflow Analyzer Sudden Not Show Last Hour Application Data

I am using Linux based Netflow Analyzer build 9860 with embedded MYSQL. All was working fine but since few days i have observed that devices interface graphs are working fine and but APPLICATION HOURLY graph is not displaying while 6 Hours APPLICATION graph is displaying fine.

I also noted that huge incoming input / out traffic on NETFLOW ANALYZER Server loopback interface but when i shutdown netflow service said traffic will be claim. 

Kindly find the attached files of Hourly graph and 6 hours graphs for your reference.

Kindly advice me for the same.
