stability of Cobalt Qube 2

Dear list,

I am a proud owner of a Cobalt Qube 2 (http://kennywest.blogspot.com/2010/02/story-of-cobalt-qube.html) running Debian Squeeze. I want to use this as a NAS device for backing up various Linux machines on the network (I want to do this using mondo over NFS). Apparently this proves more difficult than I thought (see also: http://lists.debian.org/debian-mips/2012/03/msg00015.html). Seems the Qube 2 dies under heavy network load. So whenever mondo tries to upload the restore images to the NFS server, it starts to hang. Also tried using a newer network card (since there is a free PCI slot anyway), still the same issue.
So, I was wondering, what if I tried NetBSD, would this be more stable? Are there people on this list using a Qube 2 reliably?

Many thanks for your input.


regards,

Kenneth
