PROC UNIVARIATE might hang or abend with an error message such as the following:

ERROR: Read Access Violation In Task [ UNIVARIATE )

If an INSET statement is specified following a HISTOGRAM, PROBPLOT or QQPLOT statement and the input data set is moderately large.

To circumvent the problem, the INSET statement must be omitted. If SAS/QC is installed, PROC CAPABILITY might be used instead.
