Has anyone seen some connection instability with the GlobalProtect VPN client (v1.2.2-14), on OS X 10.9 (Mavericks)?

Strangely, I see frequents drops of my entire WiFi connection (to an AirPort base station that's been solid before now) including to local (non-VPN'd) nodes as soon as I initiate the VPN connection (which also has been very solid before now).

Any clues?
