This seems to be a weird config, you have CentOS 5.4 (released 2009 with a 2.6.18 kernel), but you are running a xenified Fedora kernel compiled in 2008. Is this some kind of Amazon instance, like EC2 or something? Did you cloned this from a community provided AMI, like @ [1]? A fresh, updated and vendor supported (!) OS would certainly not hurt. Just think of what kernel exploits you have in a kernel from 5 years ago, a part from the problems you are seeing with haproxy.
