Arquivo Discussoes de Programacao e Tecnologia Bom dia,
estou enfrentando um problema que a principio parece ser de timeout. Todos os dias pela manhã é necessário reiniciar o tomcat por que a aplicação que roda neste servidor perde a conexão com o banco de dados. Alterei algumas variáveis no mysql:
wait_timeout | 86400
interactive_timeout | 86400
mas não adiantou. Estou utilizando mysql 4.21 e tomcat 5.5.23, o java é 1.6. Utilizo o drive mysql-connector-java-3.1.10-bin.jar , alguem conhece este problema ?
Não poderia estar estourando o pool de conexões, ao invés de ser um timeout?
Tens como postar o erro que te aparece?
Este é um trecho do log do tomcat:
