WordPress + Walrus = Broken Servers

[walrus]

This time I'm totally confused. Sunday, Nudes Artistically Done stopped responding. I hadn't really done anything other than post and upgrade a couple plug-ins but that was hours before the problem started.

To make a long story short:
I don't see how it can be a script problem as I've uploaded wordpress twice.

I can't see how it's a plug-in problem because I'm only using plug-ins that are running day in / day out on other blogs on that server and I'm running a very limited set of them

I can't see how it is a theme problem as it crashes running the default kubrik theme.

And yet, my host doesn't think it's the server because all my other sites are working fine and they are on that server but yet everytime they need to reset apache to get things running again.

I am at wits end.
