Different results with Fortran programs on File systems

   Hallo,
    OS : Tru64 V5.1A (both machines - ES40 and AlphaServer 1200 5/533 4MB )

    Iam getting different output on 2 file systems from 2 different
machines. I have exxported
    2 file systems from 2 machines (ES40 and AS1200) to an AlphaServer
4100.(psw400)
    I have checked the NFS status of both machines with sysman. Both shows
the same results.
    ON ES I have Patch level 4 installed and on AS1200 Patch level 3.In
/etc/exports I use
    the same syntax:

    /home -root=0,access=psw400

   When I run the following program on psw400 I get different results:

   c
        program search
      c1 = 1.e00
      c5 = 5.e00
c
      open(3, file='gr.inp', status='unknown')
      write(3,'(1x,e12.5)') c1
      write(3,'(1x,e12.5)') c5
      close(3)
c
      open(3, file='gr.inp', status='unknown')
      write(3,'(1x,e12.5)') c1
      write(3,'(1x,e12.5)') c5
c
      end


    ON ES40 (mount point on psw400 : /mnt)
   ================================
      0.10000E+01
      0.50000E+01

   On AS1200 (Mount point on psw400: /mnt)
   ================================
    0.50000E+01

   The first line is missing !!!!!!!
<--------------------------------------------------

   To shorten the mail:

   Exported FS; /home
   In /etc/exports file: /home -root=0,access=psw400 (on ES40 and AS1200)
   username : root
   mount point : /mnt on psw400
   Fortran version on psw400: Compaq Fortran V5.5-1877
                                               Compaq Fortran Compiler
V5.5-1877-48BBF

   Patch kit on psw400: T64V51AB02AS0002-20020513 OSF520

   Using AdvFS on all machines.

                                          ES40
AS1200
                                          ====
=======
OS: v5.1A
v5.1A
Patch kit 4
3
NFS on both machines is having the same configuration.


     
     I have noticed also another point. If I run the above program on a
File system exported from an AS4100 where no
     patches installed, I donot get any errors.

     Now I donot know where and how to analyse this problem. I donot know
whether I have missed any more information
     in my mail.
