No sé porque se me acaban las conexiones disponibles.... se supone que tengo habilitado un pool con 50 y no existe tal numero de conexiones nunca durante el funcionamiento del servidor de webservices... pero dice que ya no puede obtener una mas.... y después ya no responde ninguna solicitud. Aqui la salida de la consola.. y la confiuracion en el archivo standalone.xml referente a la conexion DefaultDS Bueno la verdad es que necesito algun apoyo para empezar a buscar porque pasa esto...
