Hi All

We've been hit by a weird deadlock which it took me some days to isolate and replicate. It does not have to do with order of updates or any explicit TABLE-level locking, the objects/targets of the deadlock in question are transactions.

First off, I maybe wrong with the above conclusion, I noticed that

Hi I reproduced without the triggers, I understood the problem, I believe the system's behavior is the intended, I am sorry for the false alarm. The thing is that it takes >=3 transactions to happen . That was the tricky part, up to now in all cases of deadlocks we had two transactions involved, this one needed three or more.

For folks that run across this thread what was the issue?
