</span>Here you should use the --restore-detached option. It will make criu exit<br>
after restore and re-parent your app to init process.<br>
<br>
Additionally, you can use the --pidfile <filename> option and criu would<br>
print the restore app's pid into the file named <filename> :)<br>

><br>
> 1) checkpoint app -> (2) restore it -> (3) than checkpoint again -> (4) than restore again -> (5) than checkpoint again -> ......<br>
><br>
> I am trying a pattern like this; but when I restored the application at step 2 than I cannot find the app to checkpoint again in ps but I find the criu running (which I am unable to kill/stop).<br>
><br>
> Note I am using the simplest example (bash script) stated in the CRIU How Tos.<br>

> Please comment on the possibilities and fixes if possible.<br>
