Alan,

This is somewhat reminiscent of the problems I've had with NFS over the
past several weeks. Files will sporadically get truncated, or filled with
garbage. Once, the copy ended up with 0 length.

Apparently, no one else is seeing this. I did let Bill Hawes know in case
he wants to post a patch to trace for it.
