Error description
A Linux NFSv4 client may hang when accessing an AIX NFSv4 server during file access. The iptrace reveals an infinite loop during the NFSv4 SETCLIENTID_CONFIRM operation with the AIX server returning the NFS4ERR_EXPIRED error. This has been seen at least on Red Hat Linux V6.3 client.
Local fix
