Here at SAS Mecca, we run a lot of Socket Services with a one-to-one relationship between the SAS Broker and a SAS App Server, and we run several Pool Services (as previously described); but we do not run any Launch Services. We very, very rarely have any issues with the pool servers hanging. However, every great once in a while we do get a hang in a socket service app server. Those can mostly be remedied by a simple restart. However, here and there over the years, we have had some stubborn ones that we had to work hard to kill.

So, I think that the SAS/IntrNet software has become more reliable, durable, and robust over the years. We are pretty pleased with it.

Jack, best of luck in all your SAS endeavors!

I hope that this suggestion proves helpful now, and in the future!
