Estimated scratch disk usage Gaussian error

Hi,
 I wonder if somebody could help me with the following problem:
 Gaussian 98 - computing the MP2/aug-cc-pvtz (or Ahlrichs TZVPP) frequencies
 (i.e. 2nd derivatives) for the thymine+water system (10 heavy atoms, 8
 hydrogens) crashes with the following error message:
 ********
 Disk-based method using ON**2 memory for 14 occupieds at a time.

 Inconsistency from DE2Siz in DoE2D.

 I am using 1200 MB of memory, 1 CPU, and
 %rwf=s/a,2000MB,s/b,2000MB,s/c,2000MB,s/d,2000MB,s/e,2000MB,s/f,2000MB,s/g,2000MB,s/h,-1
 (the last -1 means that any and all available space may be used)
 I've already tried changing the memory, NProc, and %rwf, but with no
 succes. Did anybody encounter the same problem? Is it a problem with the
 space requirements?
 Thanks in advance
   Dan
