 Subject:  openvpn crash
 Date:  Tue, 20 Jun 2006 21:22:52 +0200

When my SIP phone tries to connect to the proxy through openvpn-tunnel 
and the service isn't available openvpn seems to crash. I get this on 
the console:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x616f6c64
fault code              = supervisor read, page not present

syncing disks...
Uptime: 11s
Automatic reboot in 15 seconds - press a key on the console to abort

Normally I use net4801 as platform, but I run this one on a pc to see if 
there was output on the console. Most of the time m0n0 just hangs - but 
now and then the above message is printed on the console.

The image is  1.21-ovpn1 but the issue is te same with earlier releases 
too. Is this a m0n0, BSD or openvpn issue?
