CCL: Gamess Error Question

 Sent to CCL by: Michael Ver Haag <verhaag<*>csd.uwm.edu>
 I am relatively new to Gamess and I have occasionally gotten
 the following error
 PWRT: NODE   0 ENCOUNTERED I/O ERROR WRITING UNIT   8
 EXECUTION OF GAMESS TERMINATED ABNORMALLY
 I am running gamess on a Mac G4 with OS 10.3.9
 In the past I have gotten these calculations to work by moving the files
 to other computers which leads me to think that this is a permissions
 problem, but I am just guessing.
 Anyhow my input deck looks like this, any help you can give would be
 greatly appreciated.
