Problem Description: 

 Note:
     As a point patch, this fix is not currently scheduled nor
     will necessarily be approved for intergration in a future
     PC-NFS release.

 1201047  If you are using a Solaris 2.x server with pcnfs5.1 you may run 
          into file corruption on the server.  the problem has to do with 
          the larger size of the Solaris 2.x duplicate request cache and 
          the XID generation on the pcnfs client.  In short, pcnfs.sys 
          doesn't increment the upper word of the XID so that it cycles 
          through 64k of xid's. When the XID's roll over and continue to 
          send RPC's to the server  you may hit a case where the server 
          will reply with a cached response.  Modified code to increment
          upper and lower word of XID.
