The bug exhibits itself as follows: a rename(2) call returns -1
(errno = 2, "No such file or directory"), but the file DID exist
before the call, and has now been SUCCESSFULLY renamed. This sort of
false error report explains the lossage in sortm.
Off hand, this sounds like the NFS non-idempotent problem: client sends
rename request to server, server sends ack, ack gets lost, client
resends rename request to server, server sends error message to client.
