G94:disc space exceeded during AO/MO transformation

[nieder %-% at %-% rs3.thch.uni-bonn.de (Christoph Niederalt)]

 Dear Netters,
 I'm having a problem with Gaussian94 attempting to run a CIS
 single point calculation. Using 238 basis functions,
 the 2GB disc space is exceeded during the transformation
 of the AO integrals to the MO basis in link l804.
 The output ends with the message:
    Semi-Direct transformation.
    ModeAB=           4 MOrb=            24 LenV=       2893898
    LASXX=     31075194 LTotXX=    31075194 LenRXX=    62877810
    LTotAB=    31802616 MaxLAS=    40782816 LenRXY=           0
    NonZer=    93953004 LenScr=   143823404 LnRSAI=    40782816
    LnScr1=    64068122 MaxDsk=          -1 Total=    311552152
    SrtSym=           T

 If I try the keyword "transformation=fulldirect", I have not
 enough memory.
 With the keyword "cis=direct" the transformation is avoided
 and everything works fine but I need the MO's !!!
 Can anyone suggest a trick to complete the transformation?
 Thank you very much for any help,
 Christoph Niederalt
