Did you contact Tech support?

The address is support-at-sas-dot-com. 

Include the output of proc setinit in the email.

I suggest you follow the advice in the log and track this to SAS Tech Support. A read acccess violation is a pretty serious error and it means the SAS procedure cannot properly handle your data and procedure settings.

You could also try running this with a much smaller sample of data to see if that helps.
