CCL: counterpoise in gau 09



My job makes geometry optimization, then reads geometry from the CHK file and computed binding energy via counterpoise.

Sporadically, I get the following problem:


Counterpoise: doing DCBS calculation for fragment   1 NewBq=T
 NInts<0 in InToWP.


I have been never getting this while not reading CHK file.


What does the error mean, please?
