Backups? Congestion on the network due to a site that's only accessed heavily
at weekends?
There are no backups. The website uses DB2 which is backed up infrequently.
And all of our users use the site during business hours on weekdays.

No. The JVM collects garbage at intervals measured in seconds or minutes, and
takes milliseconds or seconds. It also doesn't know about weekends :-).
I forgot to mention that there is an apache/mod-jk load balancer in the front
end. On weekends we end up restarting everything including apache and jboss.

I'd guess system maintenance of some kind. Is this on a physical server or a
virtual one?
There is no other system maintenance more than what I have mentioned. The
Tomcat runs on a physical server. Heard a virtual server will be even slower.
