I'm using UDP sockets for a USB device driver to communicate between my application server. The driver runs fine in fedora8(no crashes when talking to application). Since I have other issues in fedora8, I'm trying with xubuntu 8.04.

In xubuntu 8.04, The driver log shows these messages. It crashes almost always after starting the application. I don't see these AppArmor hooks in fedora 8. Is this hook call causing kernel to wait and crash?

Please help.
