Diablos, se me ha colgado el proceso imapd, probablemente por un fallo del kernel
manejando la memoria virtual...

Me he asustado y he hecho un shutdown -r now, al arrancar se ha puesto a chequear
los sistemas de ficheros porque llevaban 523 días sin ser chequeados (son los días
pasados desde el último reinicio).

$ uname -s -r -v -m ; cat /etc/debian_version
Linux 2.4.33.2 #2 dom nov 12 17:09:35 CET 2006 i686
3.1

Quería compartirlo con vosotros.

Feliz Navidad.

Guau! un kernel 2.4 jeje :-)

Pues quien sabe? quizá ese e2fsck te haya venido bien porque el oops
ocurrió mientras el códido de ext3 leía una página de disco en la cache
de paginas...

Un saludo.
