Errors in log of Symantec Messaging Gateway

Hi all,

in some SMG appliances (in this case VM  with 10.5.2-3 version) I see strange error like the following ones:

• "> Moonshine: error return from add_pmc_stats.
• ">Moonshine: error in stats file received from msserver: .

I cannot find references that could explain me the reason.

Could you help me?

Thanks
