8.303 pgstat error

I had started this thread here http://www.astaro.org/astaro-gateway...1-hung-up.html
But since it is postgresql related I thought it would get more traffic here.
It has already hung up twice since applying the 8.303 Up2Date. By hanging up I mean Webadmin gives a server unavailable error when trying to connect, I can't login via SSH, It refuses to hand out new DHCP addresses. However, addresses with static mappings continue to work.
I keep getting these errors that point to postgresql.
