Сервер Ubuntu 12.04 - Как интерпретировать этот системный журнал записи об интерфейсе eth0?

Я вхожу в свой сервер Ubuntu 12.04 следующие ошибки в syslog/dmesg. Недавно сервер стал многократно медленным в сети, и порождение во время подвесило приложение и много ошибок с postgresql-9.1 сервером, работающим на нем.

Отрывок журнала от dmesg

Любая справка ценится, поскольку я должен выяснить то, что продолжает этот сервер.
