Heartbeat Caindo

Boa tarde a todos

Seguinte tenho dois servidores GW com Heartbeat instalado.
O que ocorre é o seguinte, ele cai e sobe em determinados dias, causando uma queda temporaria na internet. E voltando novamente.

A configuração primario é Debian 4 Etch, e da segunda um Conectiva 10, a ligação de uma maquina para a outra é feita via Serial.
Esse é a parte do meu Log
