kernel SUSE falla XFS-NFS?

[augusto ingunza]

Amigos:

Tengo un servidor Prolant DL380 G4 con un arreglo de 8
discos corriendo con una partición XFS y con montaje
remoto via NFS, y se cuelga esporadicamente cuando
estoy haciendo una copia a través de la red, parece
que es un problema en el kernel?
Que opinan?, y en todo caso como hago para actualizar
mi kernel de SUSE enterprise 9, tengo que comprar la
licencia?

Tengo el kernel 2.6.5-7.97-smp

Gracias
