I'm seeing this as well, with the V3 patch on FreeBSD 7.  I am 
transitioning to using mpm-peruser still, I have around around 5 server 
environments, one with ~1000 vhosts (handled by mod_vhost_alias), and ~4 
vhosts in their own individual server environments.

I'm also seeing some segfaults, but I haven't dug in enough yet to see 
where they're coming from.  Does anybody have any advice on tracking 
that down?

PS - Great work on the patches, despite these problems, things appear to 
be generally working well.
