Thanks to Jesse Carroll for the information about where to
find the Sys Admin Guide for a Netra X1.  Russell Neisz
supplied information about how to determine my process
limits.   David Evans suggested checking the site of the
FlexLM provider ( as he had this
problem on an MS system several years ago.

The Netra X1 Sys Admin Guide is at "" under
the Telco" heading (obvious, right!).

No one came up with a way to delete the defunct processes
other than rebooting the machine.

A lot of people suggested that I go in and kill the parent
process of the defunct processes and that should clean them
up but the parent process no longer exists.  I had a bunch
of defunct processes with PPIDs that no longer exist.  No
one had a good explanation of how this could happen.

Late yesterday the system stopped responding to all input
and would not even respond to a stop-a sequence so I had to
reboot it by turning the power off.  That obviously cleaned
up the defunct processes but not the way I had in mind.

We are running an application that uses the FlexLM license
manager to run their own license daemon and they provided a
utility to reset the license daemon that would go out and
just kill their daemon and then rely on lmgrd to restart it
(which it did).  I think this is what was causing the
defunct processes so I rewrote the script to use "lmdown"
and "lmreread" to shut down and restart their license
daemon.  I have not seen any defunct processes since.
