I am also experiencing it. No big deal, not self-mending, just annoying. Started on 3.3.8, after I have moved folders with data created on 2.03. Disappeared after correcting page settings:
-mainpage URL corrected
-flush all caches executed
So may be one of the above causes incorrect communication with GS server.
