CCL:G: ESP-derived-charge error messages

 The problem is that you have tried to write information to the disk, and
 have exceeded the limitations in Gaussian.  If you are using a 32 bit
 machine, the program limits you to writing 16Gbytes of space on the hard
 drive.  MP2 uses a lot more disk space than B3LYP.  The Gaussian manual
 shows you how to save .rwf files in 2 GByte segments.  Do what the
 manual says, and then watch the rwf.a, rwf.b, files fill up.  If you get
 to the limit you will have to do the problem over on a 64 bit machine.

 Dear all,
  I was trying to run an ESP-derived charge calculation in Gaussian 03
 for my sytem at single point calculation at MP2/6-311++G(d,p) pop=mk
 iop(6/33=2) iop(6/42=6)level on the optimized geometry calculated at the
 level of B3LYP/6-31g(d,p). My system is a novel base-pair consisting of
 85 atoms, including six N atoms, four P atoms,twenty three O atoms.  The
 sugar is a D-allopyranose .I got the following error messages--, "
 Erroneous write: write -1 instead of 4096, fd=4, orig len=4096
 left=4096, g-write, "
 Can any one tell me the significance of this messages and how to solve
 it ? . Ofcourse, when I used B3LYP/6-311++G(d,p) the job terminated
 normally.
 Thanks in advance,
