SONAR getting definition failure daily but no actual problem seen

Hi All,

Two of my 2008 R2 servers' SEP client are generating SONAR erros daily during the definition update time, like the following:

- SONAR has generated an error: code 0: description: Definition Failure

Though at the next second it shows the following event:

- New virus definition file loaded. Version: 131126002.

And opening both of their SEP clients I still get a green tick saying no problems have been found.

I am wondering then is the SONAR error ignorable? Why does it keep happening daily?

Grateful if anyone could kindly provide some pointers to stop this error from appearing.

Thank you for reading!
