 insufficient virtual memory

Has anyone dealt with the error message:
forrtl: severe: insufficient virtual memory

I first thought this error message indicated insufficient swap
space on the machine I was compiling the program.  I then
tested this on many different machine (ones not on the same
local network) and got the same message.

Some vital information:
OS: ULTRIX V4.4 (Rev. 69)
Compiler: DEC fortran compiler (f77)
Input file size (unformatted data file): 4658836 bytes

The error message occured after the following READ statement:
      data ku /10/
 10   read(ku,end=500) job, nymd, nhms, nymdo, nhmso,
     &                 xlabel, im, jnp,
     &                 nsfld, nufld, ndfld,
     &                 ptop, nulev, (zlev(k),k=1,nulev),
     &                 nlay, (sige(k),k=1,nlay+1),
     &                 ndum, (ddum(n),idum(n),rdum(n),cdum(n),n=1,ndum)


Thanks for your help,
Kevin

I've found a solution!  I didn't know that the data I was reading
was BIG ENDIAN.  The DEC Fortran compiler (f77) has an option
so that your program can read BIG ENDIAN format:

 % f77 -assume big_endian file.f
