Alan followed up with me but we did not reach any conclusion as to what

as far as copying files and such. For you, is it on a particular box or
boxes, have you tried copying the other direction? I use NFS over UDP btw

# mount
mount:/disk/1 on /remote/1 type nfs

Are you both using NFS + software RAID? Is 4KSTACKS enabled?

IIRC people were getting stack overflows with the NFS + RAID + 4K stacks


I was not using any type of RAID, SW or HW.
4K stacks was not enabled on either machine.

I am using XFS though.
