Re: XFS NFS server Oops

["Ian D. Hardy" <i.d.hardy@soton.ac.uk>]

Steve,

Thanks, I'll try to get the latest XFS CVS kernel and this patch compiled
up and tested (on our development server) tonight/tomorrow and get it on our
production server in the next couple of days. Fortunately (though in testing
new versions/patches frustrating) it can be anytime between 2 hours and
2 weeks between crashes on our production server so it will be some time
before I can say with any certainty if this is the fix.

Will keep you informed.

Thanks

Ian
