NFS replication & Failover errors

Hi All,

We have been having this problem with NFS failover.  Today we suffered an issue which caused our clients to failover to the secondary NFS server.  Every time this happens, we get these warnings

Oct 28 10:09:24 web47t nfs: [ID 694808 kern.notice] NOTICE: NFS: failing over from nas1 to nfs2

The files are read-only and they are the same... is there some checksuming file or state file that could be cleared out during a failover?  

Any ideas why NFS thinks they are not the same files?
Were running Solaris 10 X86
nas1 is a EMC/Dell Clarion CX-600

This message is printed when the type and size of the files do not match.

yes...i know that, but the file ARE the same.. doing checksum's and they are exactly the same...size/mod date/checksum

and other ideas?
