As Bas already told: we have a production site with 2 (identical) servers, configured as loadbalancer. At first the network problems occurred at the primary loadbalancer, but after rebooting that one the problems migrated to the second server. Only after rebooting both servers with the previous kernel our servers became accessible again.
