 What makes it worse or harder to track down is it seems to be momentary
problem.  While this process hangs, others are connecting
no problem.  It's almost as the Listener drops a packet or something to
that effect and the DBI connect is still waiting for it to return.  This
is a high traffic DB so it may be easier to work around, unless the
problem worsens.  Trace files would be huge.   

[rr]  Do other processes experience this issue?  I suggest this course
of action because it only happens at a certain period of the day/night,
and because you do not seem sure where the issue is.  If the program
cannot contact the DB (i.e. the dedicated server process is not
created), then a trace file will show this (actually, it will show
nothing).  You could then move on to setting listener trace parameters.
Of course, this runs the risk of creating many large files and slowing
down your listener connections, but, at least you will be closer to
discovering the problem.
