The problem is that there is no reliable way how to get correct FQDN. There is unreliable interface getdomainname() which returns on many platforms empty string or often default domains like "localdomain", "mydomain" when no other specific domain was set during system installation. The getdomainname() takes the value on some platforms from sysctl, on other platforms from file in /etc/ and on other platforms it's completely ignored. The name service lookup is not reliable as well - it depends on how the name service was set (usually NSS switch uses local files first which often have the shortname in front of longname for the given IP address and thus return often shortname first).

Ok great! I think I have a solution. For me this reduces the bug from 1 in 5 times, to around 1 in 1000. I still see the bug but this helps a bunch: ======== My Almost 100% Solution!! ======== Edit /etc/inittab. Comment out all of the normal tty's (they are unused in PV mode). For example: Code: #1:2345:respawn:/sbin/mingetty --noclear tty1 #2:2345:respawn:/sbin/mingetty tty2 #3:2345:respawn:/sbin/mingetty tty3 #4:2345:respawn:/sbin/mingetty tty4 #5:2345:respawn:/sbin/mingetty tty5 #6:2345:respawn:/sbin/mingetty tty6 Near the end of the file, there (may) should be a cons entry. Comment it out as well Code: #cons:12345:respawn:/sbin/smart_agetty -L 42 console add this line to the end of inittab: Code: co:2345:respawn:/sbin/agetty xvc0 9600 vt102 From XenCenter: Right click on the VM, click Startup Options. Replace all the text in OS Boot Parameters with this: Code: xencons=xvc console=xvc0

Create the following file if necessary: File: /etc/sysconfig/network/routes # Destination Gateway Netmask Device 66.246.75.0 0.0.0.0 255.255.255.0 eth0

0.0.0.0 12.34.56.1 0.0.0.0 eth0

A quick look at the available modules in /etc/apache2/mods-available showed me that in addition to mod_proxy.so I also had

mod_proxy_http.so. On a hunch I decided that mod_proxy_http.so was the best candidate so I tried that first.
