In cases where virProcessKillPainfully already reailizes that
|
|
|
25aafc |
SIGTERM wasn't enough we are partially on a bad path already.
|
|
|
25aafc |
Maybe the system is overloaded or having serious trouble to free and
|
|
|
25aafc |
reap resources in time.
|
|
|
25aafc |
|
|
|
25aafc |
In those case give the SIGKILL that was sent after 10 seconds some more
|
|
|
25aafc |
time to take effect if force was set (only then we are falling back to
|
|
|
25aafc |
SIGKILL anyway).
