help about gaussian



Hi, all:
 I am doing the geometry optimization of a system with 132 atoms. and I
 used the keyword "opt=modredundant" to constrain some distances and
 dihedral angles. the input file is like following:
 ****************************
 #T RHF/6-31G(d) Opt=ModRedundant Test
 Test
 0 1
 C  0.1 0.1 0.1
 ..............      //the XYZ format coordinates
 .............
 .............
 N1 N2 N3 N4 F       //the constraints, about 32 constraints in total
 N6 N7 F
 ........
 .............
 ************************
 the calculation stopped after 8 hours and gave the error message like
 this:
 **************************
 ShPair-CalcS2-2 allocation failure:  iend,mxcore=   3448329   2993230
  Error termination via Lnk1e in
 /usr/local/stow/Gaussian-linda/g98/l701.exe.

  File lengths (MBytes):  RWF=  598 Int=    0 D2E=    0 Chk=   21 Scr=    1
 **************************
 Could anybody tell me what is going on here? Thank you very much.
