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
N/A
Problem summary

Problem conclusion
Client record time is renewed when the DELAY error is returned to the client. this will make sure NFS4ERR_EXPIRED error not returned to client.
Temporary fix
