I don't see, but have you thought to check the following points ?
Did you check that the file system was not full (df -k .) ?
Or there may be a limit to the domains, so grep the source code (or the
configuration files ?) with the maximum number of working domains ?
If your filesystem where httpd.pid is were mounted by NFS, with no root
special access, it could explain a little, but if it works when you reduce the
number of domains, it's not that.
Hope it can help you or someone other...
