    Thanks, @serg38.
    Looking at the SQLs you posted. We could start to discuss whether or not some SQLs statements
need locking transactions.
    Ignoring Deadlocks 3 and 4 for now, I think we could start with the ones the look the
simplest (Deadlocks 1 and 2). 
    These SQLS have probably being generated, so tracking them on ACS may not be that easy,
but at first glance, I feel that we could execute them without needing lock in the database.

    I tried to find the first SQL, without success. Would you mind helping me pin point where
in the code the SQL from transaction 1 at deadlock 1 is generated? Then, we can evaluate if
it is or not needed a lock there. 
    Are the SQLs you showed complete? I found a place that could generate SQLs similar to
the one at transaction 1 and deadlock 1, but this code adds one extra where clause.
    The method I am talking about is:,
