Error description
When no version is specified during the mount operation, AIX NFS client starts with vers=3. If there NFS server responds to the MOUNT NULL call, but does not reply to the NFS NULL call, then this could cause the NFS TCP connection to remain active (socket is not closed). The following command will show a lot of connections on reserved ports to the same NFS server. (the local IP and server IP remain the same) # netstat -an | grep 2049
Local fix
Specify vers=3 during the mount command. If the MOUNTVERS3 works, but NFSPROC3_NULL doesn't then we could still get in to the same condition, but it is less likely for a server to not support vers=3, as compared to vers=2.
Problem summary
NFS TCP connection remain active and leading server unresponsi ve over the period of time.
Problem conclusion
Memory leak of TCP client handle is fixed.
Temporary fix
