kill_ignore token in seos.ini determines whether to ignore (deny) kill command directed at any one of the three main CA Privileged Identity Manager (PIM) daemons and the default value for this token is yes (ignore).
System shutdown may cause system freeze if PIM is running and kill_ignore is no.
If kill_ignore is yes, PIM ignores kill command from OS on shutdown but PIM terminates the daemons gracefully on OS shutdown and OS shutdown proceeds without problem.
However, if kill_ignore is no, PIM accepts kill command from OS on shutdown and the daemons are forcibly terminated.
This may cause deadlock and system freeze as a result.
Workaround is one of following:
set yes to kill_ignore
stop PIM before OS shutdown (manually or automatically)
