Strange behaviour of django webapp on dreamhost

[Marco Pantaleoni]

Hello!
We have a simple web application hosted on dreamhost.com. Our customer
has started complaining about some intermittent problems. This happens
most of the time between 9am - 11am PDT. From the error e-mails
received I see that the server raises a ViewDoesNotExist exception,
but with different views and error messages every time.
For example, the first email reports:

ViewDoesNotExist: Tried v_artists in module fioretto.portal.views.
Error was: 'module' object has no attribute 'Model'

the second:

ViewDoesNotExist: Tried v_artist in module fioretto.portal.views.
Error was: 'module' object has no attribute 'v_artist'

(the views v_artist and v_artists are present, and usually work!)
I attach the two emails for reference.

Also in the log files on the server I see various error messages, like:

TemplateDoesNotExist: 404.html

File does not exist: /home/fioretto/galleriafioretto.com/admin_media/css/null

ViewDoesNotExist: Tried django.views.defaults.server_error. Error was:
'module' object has no attribute 'Manager'

The applications runs with FastCGI and django r2998 (post magic-removal).
I've asked to the dreamhost support but they can't help me. Do you
have any idea?
What am I missing?

Thanks in advance.
Cheers,
Marco

Dreamhost has come up a fair few times for funkiness issues, with Django.

Personally, I moved my business web site (still coming) to webfaction, and
that's where I get my clients hosted too. The support is excellent and
understands django, and there haven't been flakiness issues.

Dreamhost is a lovely place to play around a bit with Django, but I couldn't
recommend ever hosting a client's website there.

I highly recommend you subscribe to Dreamhost's status RSS feed
(http://www.dreamhoststatus.com/feed/).

They've been having some well documented network and system issues
recently, and have recently done a bunch of *massive* hardware
swaps/upgrades to solve the problems.

I was seeing horrible MySQL access times on one of my Dreamhost
accounts (with Django), but after the upgrades it seems to be ok.
