Cause

El dispositivo PowerProtect utiliza PostgreSQL para realizar algunas de las funcionalidades internas. Se producía un problema de agotamiento de la memoria debido a demasiados procesos de Postgres en ejecución y a la inundación del archivo /var/log/messages con entradas de proceso de kernel repetidas. En una instancia, había 422 procesos de Postgres que usaban 15 GB de memoria en el dispositivo PowerProtect. La condición Postgres hizo que el archivo /var/log/messages consumiera el espacio de disco restante (por ejemplo, 11G) en ~14 horas.
