Stopped CPIC and Note 387598

We've just upgraded to ECC 6.0 and have seen one occurance of all our dialog and updates being held up in a "Stopped CPIC" status. I've read note 387598 but am unsure how to check if the number of APPC blocks was really the cause.

Does anyone know where to look to see if the Stopped CPIC problem was really caused by a lack of APPC blocks?

thanx
