Thanks for responding, Askar. I saw that thread, and those fixes are not working for me. My system already had the nosegneg file in /etc/ld.so.conf.d (it was installed there along with the kernel, so that issue has been fixed in the sources), and ldconfig shows that the system knows about it: # ldconfig -N -X -p | grep libc.so libc.so.6 (libc6, hwcap: 0x0018000000000000, OS ABI: Linux 2.6.9) => /lib/i686/nosegneg/libc.so.6 libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6 The messages are coming from non-mono processes, so that's not it either. Perhaps a problem with dual cpu being used with Xen and FC6? Is there anyone else out there running Xen and FC6 on a Core 2 Duo who can report not having this problem? -- Jim On Sun, Jan 21, 2007 at 09:20:02PM +0500, Asrai khn wrote: > Date: Sun, 21 Jan 2007 21:20:02 +0500 > From: "Asrai khn" <asraikhn@xxxxxxxxx> > To: fedora-xen@xxxxxxxxxx > Subject: Re: "4gb seg fixup, process X" on FC6 dom0 > > > Yes there is a fix for this you can find the solution in the archives > http://www.mail-archive.com/fedora-xen@xxxxxxxxxx/msg00053.html > Thanks.
