A new FAQ entry?

This is really a three pronged question:

   1. Do we have a project FAQ?
   2. Where is it? on daisy?
   3. Should we put this as a new entry?

Someone on the users list asked about problems scaling Cocoon--Tomcat 
was crashing with OutOfMemoryErrors even though plenty of RAM was made 
available using the -Xmx.... parameter.  We pointed him to JVM and 
garbage collection as a possible culprit (as well as pool sizing).  As 
it turns out, the JVM parameters were the issue.  With proper tuning of 
the JVM (and an upgrade) they have been happily stable ever since.  It 
didn't really have anything to do with pool sizing.

The thing is that this issue is not a Cocoon issue, but a JVM 
configuration issue.  Nevertheless it is not intuitive, and pointers to 
how to configure the JVM would help others in his situation.

(assumption - there isn't a FAQ already)

I use Daisy on an in-house project for documentation. One of the things 
we have done is create a FAQ document type which has a "question" and an 
"answer" part and a category field (user, developer, installation etc.)

We then use the query facilities on daisy to automatically create a 
variety of FAQ documents.

One advantage of this over having a normal document listing the faqs is 
that you can include each FAQ in other documents. For example, by having 
a field "commonality" wich is set to "uncommon" or "common", we can use 
another query to include the common FAQs on relevant pages, e.g. the 
install documentation can includes the common install FAQs at the end, 
whilst the "uncommon" ones appear in only in the list of FAQs.

I could set this up on the Daisy instance if you like. Perhaps just 
starting with the basic FAQ doc type for now.
