Estou executando um Apache tomcat + mod_jk 1.2.40 atrás de um servidor web apache.
Tudo foi configurado e funciona adequadamente por algum tempo desde a inicialização de um tomcat (mensurável em dias / semanas); então algo acontece, e mod_jk perde a conexão com o tomcat.
Além do que acontece (na verdade, não tenho certeza do que acontece, estou solucionando problemas), estou procurando algum suporte sobre o motivo pelo qual a conexão entre o jk e o tomcat é perdida. Aqui segue a parte dos logs mod_jk em torno do problema de conexão perdida:

Eu acho que "mod_jk / 1.2.40 inicializado" significa que o mod_jk está iniciando: se eu reiniciar o tomcat, tudo funcionará corretamente novamente por dias / semanas.
Você poderia me dar alguma sugestão? Obrigado
