LOG with Update Option Values

Hello,

last week update my vCenter from 5.5 to 6 and add my enviroment new host with ESXi 6, I use this host for deploy pool with NVIDIA GRID K2, from add new pool I see in log every 10 minutes this "Update Option Value" with state "Completed", I try somethings about it but found only post with "error", on my side I haven't error but before I never see this. I have CRBC in enable on this host.

On host with 5.5 I not have this.

Can you give me some info about it ?

Thanks

M.
