Although it should never happen, all the nfsv4 server can do when it runs out of clientids is reboot. I had replaced cpu_reboot() with printf(), since cpu_reboot() doesn't exist for sparc64. This change replaces the printf() with panic(), so the reboot would occur for this highly unlikely occurrence.
