CCL: Help with interpretation of Gaussian error message?



Hi --
 
What does this Gaussian03 error message mean?
 
Fock matrices will be formed incrementally for  20 cycles.
 Integral accuracy reduced to 1.0D-05 until final iterations.
 Inconsistent input #3 in SPerMO.
 Error termination via Lnk1e in C:\g03w\l502.exe at Thu Oct 16 15:12:38 2003.
 Job cpu time:  0 days  0 hours  2 minutes 12.0 seconds.
 File lengths (MBytes):  RWF=    496 Int=      0 D2E=      0 Chk=      1 Scr=      1
 
 
I'm trying to do a force calculation on an already optimized geometry in the presence of a field...
 
thanks!
