problema con logeo (tiempo)

[elbueno45]

Hola expertos
He tenido un problema al cual no he encontrado una posible solucion,
Tengo un logeo que trabaja con pool de conexiones y filtros para que no ingrese cualquier persona.
Funciona muy bien, me logeo, cierro sesion, me vuelvo a logear, cuando pasan 5 minutos logeado pero no lo utilizan se cierra sesion automaticamente y se puede volver a logear sin problemas.
El problema es cuando pasan unas 6 o 7 horas para ser exactos, y nadie utiliza el sistema, cuando quiero logearme despues de a ver pasado este tiempo me sale un mensaje de error, y no ingresa al sistema, lo que hago es reiniciar el tomcat todos los dias, y no voy a estar asi por siempre, espero me puedan ayudar, aqui les envio el mensaje de error
espero sus respuestas
