Well the answer to this is quite bizarre. The only thing different
about the test vserver was that it did not have a domain name.
Adding a domain name to its *conf immediately caused this
vserver to exhibit the same faults as the other ones. Removing
the domain name again let it operate properly. Removing the
domain names from the *conf files for all the other vservers
immediately let them spring into life also.

I can't believe that this is a real solution - it must be a sympton
of some other problem. Question is, what??
