It this a known issue or something with my system? I trace this by adding "set -x" into vpnc script, and I only see it's debug log during connection, but on upon disconnect / shutdown.

See the part of the manual on SIGNALS
(http://www.infradead.org/openconnect/manual.html#heading5).

OpenConnect only does a "clean" shutdown when it is terminated with
SIGINT (e.g. with Ctrl-C when it's in the foreground), or by a
server-initiated disconnect. If it's running in the background and you
want a clean shutdown, then you need to do "kill -INT".
