[CRIU] Problem with CRIU

[Krishan Berwal]

Yes, You are right. my application is running under apparmor only.

I tried that when  i remove this security level then my application is not
working.
so can suggestion me for a mid way which leads to both?

criu under apparmor security level ? or can i avoid such security for while
when i dumping the process then again make active?
