Sorry dbdinc, as far as I'm aware there's no way to do this. You can usually identify if SAS is being run be specific users using process listing under Unix, but I've never heard of someone identifying specifically what a user is doing.
If you're having problems with server crashes and suspect that SAS might be causing it, it's probably worht talking tSAS directly to see if they have any debugging ideas. I've always found them to be extremely helpful people.
