So, not good for general history/audit tables...

No, you're hitting a classic deadlock problem. You need to follow the link to that article I provided. What's going...

Statements can certainly be the same. The question is, what the SPID of the two processes? If they're the same, you're experiencing parallelism deadlocks. If they're different, it's just two...
