Given a choice, which version of Tomcat would you recommend?
We have a commercial application, based on Tomcat, that locks up about
every 6 weeks or so. The only clue I've seen, is that it fails after we
log the number of bytes read on the socket and see a value of -1 (minus
one). And we've been unable to duplicate the condition on the development
systems.
My reading of this makes it sound like Tomcat is directly serving the
users rather than having it behind an Apache HTTP Server instance.
That's generally a poor idea.
On issues.apache.org (which runs our JIRA and Confluence instances),
we use Apache Tomcat 5.5.20 fronted by Apache HTTP Server 2.2.x. We
do not expose Tomcat directly to the outside world, but instead use
mod_proxy_ajp (new in 2.2) to route requests to Tomcat. I would not
use anything less than Tomcat 5.5.20 as we identified a number of
flaws in Tomcat during our own deployment of Tomcat that we got
resolved.
James has a good description here:

FWIW, mod_proxy_ajp is the result of the Tomcat and HTTP Server guys
talking to each other (at last) and trying to replace the awful mod_jk
situation. The fact that it's bundled out of the box is a very good
thing, IMO. But, it's also much more tested, cleaner, and scalable
solution than mod_jk ever was.
