I am running a stock FC6 xen, with all yum updates through today, on a Shuttle box with a Core 2 Duo and 2GB of memory. I am getting "4gb seg fixup" for plenty of programs, including X, sh, ls, date, grep, less, ssh, su and vim. This is in dom0, with no domU running. The worst offender is X: in /var/log/messages, every five seconds it consistently logs something like this: Jan 18 19:34:59 gumby kernel: printk: 30302 messages suppressed. Jan 18 19:34:59 gumby kernel: 4gb seg fixup, process X (pid 4383), cs:ip 73:47150f2a 20,000 is typical for the number of messages suppressed. It varies in different five-second intervals from about 10,000 to 89,000. I have poked around on the net and searched through the archives for this group, without finding an answer. I have seen a few posts about 4gb-seg-fixup messages in domU, or from mono programs, or from older OSs that needed a "nosegneg" file in /etc/ld.so.conf.d, but none of those seem to apply here.
