Well, as it says, SAS ran out of memory!
There are a number of possibilities.
SAS has three memory size options, MAXMEMQUERY, MEMSIZE, and REALMEMSIZE. One of them may need to be adjusted. Unfortunately, that's a job that is generally done by someone with SAS experience. If you can find that person at your shop, ask them to give you a hand with changing these.
Also, do a search on your error message. I just did that, and a number of the hits discussed the nature of the model (I'm not experienced enough with OPTMODEL to have an opinion). Perhaps your request needs to be tweaked.
SAS has a wonderful Technical Support group. I typically wouldn't send someone with your problem to them, as I don't think it's a software issue, but because of your inexperience I think it might be necessary. Put in a track with them, and see what they say.
Make sure you post back with the solution so everyone else can learn from it!
