Do they fail when you copy just those files by themselves? I once had
a circumstance where particular data inside a file could cause data to
get dropped by some network element; even doing a straight rcp on the
file would fail. It may help to examine an strace. I'm assuming the
/mnt device is over NFS, probably UDP, so it won't even help to use
netstat to examine queues or use tcpdump.
