I did some debug. I did non consider the execution of a second
transaction inside the first, this is my error.

The only way to avoid problem with my code is to lower the lock level, I
can't avoid the nesting of the transactions.

The systems works anyway two hours ago, I can't figure how to reproduce
that occasion.
