CCL: GAMESS: 'PWRT: NODE 0 ENCOUNTERED I/O ERROR WRITING UNIT 24' Error

 Sent to CCL by: Aleksey Kuznetsov [AlexKuznetsov2007||yandex.ru]
 Dear CCL Users,
 I try to perform single-point calculation using GAMESS on polyoxometalate system
 containing Ru, W, Si, O and H atoms; here is the beginning of my input file:
  $contrl scftyp=rhf runtyp=morokuma icharg=-4 mult=1 coord=cart pp=sbkjc
   units=angs $end
  $system timlim=2700 mwords=1000 $end
  $basis  gbasis=SBKJC $end
  $guess  guess=huckel $end
  $scf conv=6 $end
  $morokm iatm(1)=14 $end
  $data
 Ru2H2O2-POM, 1A
  . . . .
 The calculation terminates after a few minutes at the step of 2e integrals
 calculation, giving the following error message:
  PWRT: NODE   0 ENCOUNTERED I/O ERROR WRITING UNIT  24
  EXECUTION OF GAMESS TERMINATED -ABNORMALLY- AT Fri Apr 24 14:27:50 2009
                   1193199 WORDS OF DYNAMIC MEMORY USED
  ON NODE 0, STEP CPU TIME =   306.06 TOTAL CPU TIME =      306.1 (    5.1 MIN)
  TOTAL WALL CLOCK TIME=      588.0 SECONDS, CPU UTILIZATION IS  52.06%
  A fatal error occurred on DDI Process 0.
  ddikick.x: application process 0 quit unexpectedly.
  ddikick.x: Sending kill signal to DDI processes.
  ddikick.x: Execution terminated due to error(s).
 Can anybody please explain me what the reason of this error could be and how to
 cope with it? I use GAMESS 2006 at Linux machine.
 Thank you very much!
 With best regards,
 Aleksey.
