This happens to me also on 2.4.18 and 2.4.19 (yes, I know they are old).
Happens about once every 5 months, with the box running at
about 1 month uptime per reboot (home server, there is no UPS)

1. Dado un programa, siempre tiene al menos un fallo.
2. Dadas varias lineas de codigo, siempre se pueden acortar a menos lineas.
3. Por induccion, todos los programas se pueden
reducir a una linea que no funciona.
