Bug#405223: a workaround

[Tony Lewis <gnutered@yahoo.com.au>]

You may want to look at 
http://wiki.xensource.com/xenwiki/DebianTlsLibcDiversion.

But note also that you'll want to relocate all the /lib/tls directories 
in your vserver guests too.

Here's how I do it:

   $ for d in /lib/tls /vservers/*/lib/tls; do [ -d $d ] && echo sudo 
mv $d $d.`date +%Y%m%d`; done

Then cut and paste the resulting commands

Note that you need to do this after *every* upgrade to libc, and that 
you might also need to restart any application that was using the old 
libraries.  And you need to do it after creating every new vserver guest.

If all your vserver guests are etch-based, then you can probably install 
the libc6-xen package, and see if that solves the problem.  I have 
dapper guests mainly, and a Xen-friendly libc6 package doesn't exist, so 
I don't know if this will fix it for you.
