Well, just today I reinstall my VPS with Fedora 12 (which comes with glibc 2.11) and all is fine again. Cannot really wait for CentOS 6 to come out. I hope future builds of utserver will not go higher than that though.
Wow, you need glibc 2.11 minimum with the new version? If there is anything I don't touch in my Linux server, glibc is going to be high on the list.
