INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

In a situation where onmode -k is unable to bring down the
server, then onclean -k is used in addition, onclean would not
kill the still running oninit processes, but only 'clean up'
shared memory and semaphor resources.  As the old oninit
processes still are attached to their shared memory, those shmem
segment would only be flagged as deleted, but could not be
removed.

As a consequence nothing will prevent the instance from being
started a second time, so two sets of oninits would now be
running for this instance, and still the old instance would have
the tcp ports open (the new one would run on 'cannot bind a name
to the port' listener-thread assertions).  So data modifications
and physical/logical log traffic including checkpoints might be
coming from two independent instances to same chunks.  In
addition twice the amount of shared memory would be allocated,
potentially causing more trouble for the OS.

Kill server manually (kill -9 on first CPU VP) rather than or in
addition to using onclean -k when onmode is unable to bring down
the server.
