Dave, thanks for the step by step and the input. I will definitely try that tomorrow once my schedule calms down.
Maze, we never had issue before installing this current threads 6.3.2 We had whatever the last version # was before this one, and just didn't have a single database/missing member issue. Seems the ONLY time there are issues is when someone/several folks do a 'search'. Every member who went 'missing' said they were doing a search right before they were 'deleted'. IP says that cannot be correct, but I don't know what else to say if each deleted user indeed was doing a search prior to disappearing.
So I now have all my tables intact, NONE show any errors, they're all optimized and running fine.. .until the next time the CPU is run up and it crashes the server
