Here's some things that come to mind in terms of impact to the system and
resources:


Transient space will be consumed in varying amounts by the following things:
-NM & CM stacks
-System objects used to support a living process
-System objects used to support open files for all the open files they may
have
 including databases which have a few objects of their own (DBU, DBUX, etc.)
-CM extra data segments also used for any CM KSAM files left opened.
-Non-file objects the process itself may have created.

Any memory resident objects that the processes may have created would be a
potential
problem depending on their size and number vs. the system memory size. Any
non-
resident objects will eventually either swap out or be overlaid.

System short mapped space is a finite 2 GB in size. Most system objects are
created here
as well as short mapped files. Failure to free objects in this space can
result in premature
exhaustion of the space or possibly fragmentation of it. When S/R 6/7 space
becomes
fragmented we may be unable to create objects which require a minimum number
of
contiguous units. When that occurs various types of error messages appear
either to the
user or on the system console. It's probably quite unlikely that 62 - 64
zombied QUIZ
processes would do this all by themselves but on a heavily loaded system
they could
contribute.

System limits will be impacted. Native mode to some minor degree (I would
assume). If
these zombies are CM and you run a predominantly CM mix of applications then
these
processes could push you closer to the CM limits for extra data segments,
code segments
and so forth.

I'm certain I've missed a few other things these processes might impact by
being in this
state, but I hope this is of some assistance to you.
