I have my server for about a year and I didn't have serious problems, but it has only few services running: firewall, web cache, dhcp, ntp, nfs, dns. There is also so called "targeted policy". It protects daemons, but runs other processes in a role that has access to everything. Thus, when you want to run only commonly used daemons (that have policies), or when you choose targeted policy, SELinux isn't very hard to use.
