I think I fix the issue.
[ 22.126997] audit: type=1400 audit(1502779554.863:21): apparmor="DENIED" operation="getattr" info="Failed name lookup - disconnected path" error=-13 profile="/usr/lib/NetworkManager/nm-dhcp-helper" name="etc/ld.so.cache"
You can find that the path which is looking for is relative path "name="etc/ld.so.cache"" , so I added attach_disconnected=/ to /etc/apparmor.d/sbin.dhclient.
Sorry, it's been so long to feedback information.
