[Openswan dev] kernel panic 2.4.9 (kernel panic, pfkey_msg_parse, klips) - bug?

[Maciej Bogucki]

Hello,

>From few days I get strange crashes of my vpn device. I have changed
hardware, then upgrade kernel(now is 2.6.18) and openswan(2.4.9 now).
This machine reboots few times per day. Here is the output form console:

System is: Centos 5 with all patches with kernel 2.6.18.
Any idea how to fix it?
