2.4.21 - Oops in rpciod

[Philippe Gramoullé]

 Hi,

I happened to get this oops with a 2.4.21 (Dell 2650) running as an NFS server.
The exported partition is ~ 700Gb/reiserfs and was 99.99% full (only few dozens of megabytes left).
(Distro is Debian Sid/Unstable, RAID driver is megaraid.o v 2.00.5)

Oops occured while also running a rsync process to move data to another server.

I'd like to have your opinion on this.

Thanks,

Philippe
