I didn't have things like that, I think it is a problem with one of
your servlet, are you running some servlet ? I use only Cocoon (not
the .deb included in Debian because it is too old, I take a binary tgz
and installed in /usr/local) and Jwebmail (a servlet WebMail, a .deb
is provided by the author).

I have also the "ApJServLogFile          DISABLED (DESCRIPTOR -3)" but
things are logged (I should read the doc to see exactly why, but it's
working, so I don't care).

For the "any information logged", isn't this in /etc/jserv/jserv.conf
can do the stuff :

# Log Level for this module
# Syntax: ApJServLogLevel [debug|info|notice|warn|error|crit|alert|emerg]
# Default: info    (unless compiled w/ JSERV_DEBUG, in which case it's debug)
ApJServLogLevel notice

I've got the same (standard stuff).

I can't answer this one, I 've got just one machine and no squid proxy
cache configured in my lynx.

Sorry, I didn't installed a deb for the JDBC driver and I have not make
one (not the knowledge to make deb). But I can send you my postgresql.jar,
it is 177 ko and works with postgresql 7.0.2-4.
