If you haven't got any of these it's a good place to start to optimise your
site. Also take a look at zpt profiler, this will give you info on your page
performance and may indicate a problem template / script.

 We have plone running on an Ubuntu box that sits in the corner of the
office and has no other function or purpose than to run an internal plone
site for a fairly small group of users. For the most part everything works
fine, but every 3 or 4 days I get an email from one of the users informing
that the site is down, and is producing 502 errors. I'll log-in to the
Ubuntu box to see what's going on, and notice that the CPU is horrendously
busy, up around 85-100%, with python eating up most of the juice. But no
response from the plone site. I stop then start the instance and everything
returns to normal until the next time.

I've verified that the "Debug Mode" flag is off for both the javascript and
css management interfaces in the ZMI. I've also made sure that the
“debug-mode” flag in zope.conf is set to "off".

Here are some of our configuration details:

Plone 3.2.2
CMF 2.1.2
Zope (Zope 2.10.7-final, python 2.4.5, linux2)
Python 2.4.5 (#1, Apr 14 2009, 12:35:28) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)]

PIL 1.1.6

I don't know if this is important, but I'll also mention that our zope
database file (Data.fs) is quite large at over 5 gigs, and that the
cache-size setting in zope.conf is currently set to the default of 5000.

If there is any other information that would be helpful in diagnosing this,
please let me know! Thanks so much, guys.

Max
