I am simulating a relatively big system - 141 atoms. I have the following input file
$CONTRL SCFTYP=RHF RUNTYP=HESSIAN MAXIT=100 ICHARG=0 MULT=1 $END
$SYSTEM TIMLIM=525600 MWORDS=76 $END
$BASIS GBASIS=N21 NGAUSS=3 $END
$SCF DIRSCF=.TRUE. DIIS=.TRUE. DAMP=.TRUE. $END
$GUESS GUESS=MOREAD $END

but whenever I execute the command I get the following error

OPENING FILE DASORT WITH   183322 LOGICAL RECORDS OF  310078 WORDS
DASORT WILL CONTAIN A MAXIMUM OF   183322 PHYSICAL RECORDS OF LENGTH  310080 WORDS
DIRECT TRANSFORMATION SKIPS AO INTEGRAL STORAGE ON DISK.
***** ERROR: MEMORY REQUEST EXCEEDS MAXIMUM.
   76138666 WORDS REQUIRED     76000000 AVAILABLE.


I try to change the mwords but it still terminates with the this error.

Any help or advise appreciated

Thanks in advance

Best regards
