Problem Note 19162: Excessive time or memory required with many levels of CLASS variable
If there is a large number of levels defined by the specified CLASS
variables, PROC GENMOD may require excessive time and/or memory to fit
the model. This is most common when specifying a SUBJECT= effect in the
REPEATED statement which has a large number of levels due to a large
number of clusters in the data. But, the problem could also occur when
any CLASS variable has a very large number of levels.
