Problemas con Kernel

[Rodrigo Reyes T]

Tengo el FreeBSD release 4.7 con Squid Cache: Version 2.5.STABLE1.

Ahora el fin de semana el servidor me envio un mensaje y detuvo el servicio 
.. me gustaria que me dieran su opinion ....

Jan 11 03:30:39 trolon /kernel: (da1:ahc0:0:1:0): Invalidating pack


Para que volviera a arrancar (porque el reiniciarlo no funciono), tuve que 
dejarlo apagado unos 20 minutos y encender (COMO MICROSOFT) y anduvo.

¿Necesito comentarios... seran los discos SCSI o el Controlador?
