Nope. The call process_exists_by_pid() should filter out
non-existant process id's before they get added into the
list.

In fact they are being so removed, which is why you
don't see them under the PID title above, and yet
the call to Ucrit_checkPid() is returning true for
some reason (which it shouldn't if the pid hasn't
been entered into the Ucrit_pid[] array).

Can you gdb and break at print_share_mode()
and see why the call at :

 if (Ucrit_checkPid(procid_to_pid(&e->pid)))

is returning "true" in your case ?

Jeremy.
