Well, it’s been 10 days since I started to play with parallelism on this server. I have gotten the self blocking to stop. My CPU utilization has stabalized and my phone is not ringing. So I think that the issues is mitigated. I finally settled on Max Degrees of Parallelism of 2 and the Cost Threshold for Parallelism of 500. I also have the developers looking at the code to ensure all their joins are nolock, they tell me they should be, but I am asking nicely to them to verify. So I’m moving on to other issues unless this one pops back up.
