System Log Clutter

Hi -

I get this in my System Log frequently under Server Admin -
-----------------------
Sep 28 07:04:46 advxserve dashboardadivsoryd[27933]: fetch: advisory list is not the correct format, could not obtain being marker
Sep 28 07:04:46 advxserve dashboardadivsoryd[27933]: fetch: unable to get get sql from net
Sep 28 07:04:46 advxserve dashboardadivsoryd[27933]: fetch-parsers: parsers file invalid

How do I make it stop?
This clutter is annoying.

Thanks,

Paul
