vCenter appliance 6.0 - recurring error messages

Hey folks,

  i recently noticed some recurring error on the vCenter appliance thanks to our SIEM. I get 475 of the following messages each hour:

Oct 22 08:00:14 myvcenter vmafdd t@140038333421312: _ConfigGetInteger failed. Error code [2]. [../../../server/vmafd/config.c,1525]

Oct 22 08:00:14 myvcenter vmafdd t@140038333421312: VmAfSrvGetDCPort failed. Error code [2]. [../../../server/vmafd/config.c,328]

I was not able to find anything on Google, Bing or DuckDuckgo search engines. 0 results. (really??)

I have 3 ESXi with EVC, vSphere HA and vMotion; everything is running with no issues.

Any tip is well appreciated

Thanks
