TOO MANY ACTIVE ORBITALS: 19 THIS VERSION ALLOWS 16

ERROR EXIT
CURRENT STACK:      CIINP  CIPRO  MAIN


**************************************************
I have already gave the CLOSED card in CI
closed is 9 and occ is 24, thus active is only 15
why the program said 19 active orbitals? 

Thank you
Best regards!
