A little progress: We just had it happen again, and checked to see how
many live processes and how many zombies were involved. pstree showed
108 Zope-spawned Oracle processes, but ps showed only 55 zombies.

I assume, therefore, that the problem is not because of zombies; there
were over 50 live processes accessing oracle.

The accumulation of zombies is a problem in itself, of course, but I
understand it is also a known problem. And from what I see, it is a
separate problem.

Our impression here -- based on not much more than gut feeling -- is
that the problem is related to abandoned transactions, where an 
exception is raised.

Thanks, Dieter, for your earlier response -- we are trying a larger
cache now, and we'll see how things go.

Have fun,
