It looks like the nfs daemon is caching write data (around 2GB of it) which lets scp think its finished when actually there's loads of data sitting in a write buffer. The hanging is presumably the time it takes to flush the buffer (there is a process called nfsiod which is active during this time and df shows data is still being written).

Where the parent process is kthread.

This is from HP Tru64 UNIX. $ man 8 nfsiod http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51_HTML/MAN/MAN8/0043...
