1. Not that I know of (if so, it needs to be publicised);
closest current thing is the Wiki:
http://wiki.apache.org/cocoon/FAQs=20
=20
2. ???  (daisy would be a good spot; users can suggest=20
updates but its not as easy to change as the wiki; maybe
once questions are answered on mailing list and/or wiki,
they can be submitted to Daisy for "approval" by the dev
team in a "official" FAQ)
=20
3. Yes.

[A well-structured FAQ - and it will be BIG - is long overdue...=20
a useful reminder, this]

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=20
was crashing with OutOfMemoryErrors even though plenty of RAM was made=20
available using the -Xmx.... parameter.  We pointed him to JVM and=20
garbage collection as a possible culprit (as well as pool sizing).  As=20
it turns out, the JVM parameters were the issue.  With proper tuning of=20
the JVM (and an upgrade) they have been happily stable ever since.  It=20
didn't really have anything to do with pool sizing.

The thing is that this issue is not a Cocoon issue, but a JVM=20
configuration issue.  Nevertheless it is not intuitive, and pointers to=20
how to configure the JVM would help others in his situation.
