Xen DomU: 4gb seg fixup, process
A common error on a Xen DomU (as well as Dom0) in /var/log/messages once the guest/VDS has just been setup is:
4gb seg fixup, process
You can fix this easily by doing the following on the guest/VDS:
mv /lib/tls /lib/tls.disabled
mv /usr/lib/tls /usr/lib/tls.disabled
echo 'hwcap 0 nosegneg' > /etc/ld.so.conf.d/libc6-xen.conf
reboot
ldconfig
