For the tables and indexes, did you set degree AND instances to 1 ?
If you have degree = 1 and instances = default, it is possible (but I
can't check it right now) that this will still allow Oracle to run a
query with DOP as "degree x instances" - which in your case means
parallel 2.

Subject: how to set parallel_max_servers without running PQ within out apps
For streams, we need to set parallel_max_servers to > 1.
I made sure all tables and indexes have parallel set to 1 and then set the above
parameter.
Normal, homegrown queries started running in parallel. How can this happen if
the degree is 1 for all objects?
Is there a way to set parallel_max_servers > 1 for streams, and not have PQ
option running on our application objects?
This is a 2 node RAC, HP-UX system running 10.2.0.3.
TIA,'
