> I wasn't sure where the Blocker loosing his time, Later in the evening , I noticed that there were many ST enqueue locks (no, we are not using LMTS - For all new tables I am pushing LMTS).

Is your "TEMP" tablespace LMT or Dict? Is it of type temporary or normal? I ask this because you mention ST enqueue and this is held for creating/dropping extents in a dict managed tbs.... You might be mistaking a 'enqueue' wait for a user lock when it is actually waiting for a "system" lock (on FET$ and UET$)....
