"Erase Phantom System Health Records" being failed in job "syspolicy_purge_history"

Hi ,

I am using SQL server 2014, Jobs is successfully executing for more than a year. For few days step#3 "Erase Phantom System Health Records" gives following error:

"Executed as user: User_name. The step did not generate any output. Process Exit Code 255. The step failed."

I am unable to find exact solution.

Thanks for help.
