CentOS 5 has been running continuously since 9/21 on my "do everything" home server (with the exception of a kernel update). It's a fairly old Athlon machine that serves as a firewall and various servers (dovecot, samba, NFS, dhcp, OpenVPN, etc).
I connected via OpenVPN about a week ago and discovered I get a kernel panic. I've since found that this is very repeatable and happens only after being connected via OpenVPN for about 4 hours or so.
I was able to manually copy the stuff on the console after the panic (see below). I googled "unable to handle kernel paging request" and didn't really find anything useful (to me).
I've tried both kernel version 2.6.18-8.1.14.el5 and 2.6.18-8.1.15.el5 as well as OpenVPN versions 2.1_rc4-1 and 2.0.9 all with the same results.
Not sure where to go with this(?). Should I post this on a kernel mailing list? Or somewhere else?
