This may have something to do with the different way Linux does threads compared to UNIX.
On my RHEL5 servers I see named humming along quite happily with 5 threads across two processors so it may be the original hang problem had nothing to do with threads. I tried to find something that would document a process apparently running threads when told not to do so but couldn't. There was a change in the way threading is done by Linux between 2.4 and 2.6 kernel and CentOS 4 is based on earlier 2.6 kernel than RHEL5 so its conceivable there is kernel version issue there but if so I didn't find reference to it.
