I see this sometimes too. Only that I see in my Cron-logwatch. It says
load is too high (12 I think) and because of that it's rejecting new

I'm not sure if it prints out a DSN 4.5.1 thing.

I've never seen it _not_ working. Maybe I just don't realise it
actually, and find out later through logwatch
