Thanks! One question, does "auto growth off" option is that a good practice for tempdb? Not sure if some will argue on this. In my case what i noticed is i have 2 sockets and 2 cpus and 2 tempdb mdf files and one log file, however the problem is only 10 GB totaldisk space is allocated to tempdb drive instead of 30 GB according to your theory and cause the disk space full? Please advise if i missing anything here?
